This is the Bass boost circuit diagram for the amplifier. this circuit runs with 12 voltages. it's a mono pre-amplifier diagram.
In this article, we will explore an effective bass amplifier circuit 2SC5200 and 2SA1943 power transistors paired with the TDA2030 IC.
The following diagram is the schematic of Gibson RD Artist bass guitar Circuit Notes: Both compression and expansion effects are determined by the lead pickup output only. I and O in the design dia…
This is Bass treble circuit diagram. every amplifier need this circuit as a pre amplifier. this is mono circuit.
Already planning to build a nice bass guitar preamp tube. Now we prepared the first version. The Bassline. One valve, low component count, and good sound.

Funk is built on the bass. A great groove, when the bassist and drummer lock into one another and get everyone moving, is a beautiful thing, and easier to get ahold of than you might think. Like many great musical forms, however, funk bass...
It's New Years Eve and time for the last layout of 2019 and I'm pretty sure it's the 800th on the blog! So here's the Mostortion. Why is it called that? The CA3260E opamp at it's core is MOSFET based. Unfortunately, this chip has been discontinued, so building a straight clone may be a little difficult, but a regular dual opamp like a JRC4558 or TL072 will work just fine as well. It's pretty similar to a TS10, just with a MOSFET chip and 3-band EQ, which is pretty handy. Schematic and more info here. Should be able to squeeze it into a 1590B.
Guitar wiring diagrams: customization, DIY projects, mods. For any electric guitar. A lot of tips.
Here's the Pitch Pirate with board mounted pots. Like the Deluxe version, the LFO is designed to be grounded when the effect is turned on (hence the pad at the top of the board). Just use the true-bypass wiring diagram in the General Layout Notes and leave out the LED wiring. Then just connect the corresponding pads on the board to the lugs of the switch. The on/off indicator LED (pads at the top of the board) is connected to the LFO ground so that will turn on and off (and show the rate) with the LFO. It'll fit just fine in a 125B with top mounted jacks, but will also fit in a 1590B if you wire the pots off board (or maybe with long leg pots mounted to the component side? YMMV).
This is the Muff Booster circuit. Distortion of a very famous and popular guitar. i'm built and tested, what is the voice of this simple circuit.
Part of the last request included a cab simulator to run the headphone amp through. The ROG Condor is a great cab sim and has a fairly low parts count. It uses a JFET amplifier at the input, boosting the signal to drive the following 3 filters (Bridged-T notch filter, High-pass filter, and Low-pass filter). Much more info on the circuit can be found here, as well as a few mods. J201 apparently sounds the best for Q1, but similar DSG pinout JFETs will also work. Any dual opamps can be used for the 2 ICs, so socket and try the usual candidates (TL072, JRC4558, etc).
Many pro players swear by this tone circuit, and it indeed produces a different effect than the standard tone circuit we all know.
Someone showed me this circuit and it's a cool addition to this library. It's an old project from Electronics & Music Makers magazine and allows you to ramp up and down your volume. It's not a true-bypass pedal, but essentially an always-on boost that increases your volume when the momentary footswitch is pushed. More info and schematic can be found in these scans:
The Brassmaster was originally designed for bass and also picked up by guitarists. The circuit is very unique and originals are hard to come by. I was able to lay it out to fit in a 125B with board mounted pots.

Always a fan of the MXR Distortion+/DOD 250 as you all have probably figure out by now. Here's VFE's take on the classic circuit. Bunch of extra controls and mods including soft clipping, along with bass and tone controls. Schematic here for reference.
These circuit snippets from Tim Escobedo (RIP) has inspired so many DIY pedal hobbyists to build pedals and tinker around with circuits.

Portable Ruby Guitar Amp : I have wanted to build a small, portable amp for some time and recently come across the “Ruby Amp”. The Ruby Amp is a LM386 IC based amp and can be built to fit inside a small tin. It’s surprising powerful and rich in sound, especially seeing as th…

Being primarily a bass player myself, I've wanted to build this one for a while, but didn't really feel like messing with all the off board wiring of my first layout of this circuit. So I've drawn up a new layout with board mounted pots. I've also subbed a 2N5457 in place of the stock 2N5952 because it's what I have in my personal stock and I order from parts suppliers enough already (haha). If you do use a 5952, mind the pinout as it's SGD, whereas the 5457 is GSD.
This circuit has a single input and 4 independent outputs, each amplified with an operational amplifier.

A while back Brian Wampler shared a bunch of mods to the classic MXR Distortion Plus circuit in Premiere Guitar magazine. It adds a tone control, a switchable soft clipping stage, a compression switch, and a bass boost switch.

Here's a compressor design from MicTester. Here's what he had to say about it over on FSB: Do you remember the old-fashioned way of doing bass compression? It used an LDR across the volume control illuminated by an incandescent lamp across the speaker terminals! It was a simple method back in the 60s.... This compressor is almost that simple! It uses a handful of cheap components (I built one for £9 including hardware!), but works really well. Guitarists who've tried it often ask "Is it on?", but miss it when it's off! It's quiet, and has good "squeeze" without the gain-change artifacts you frequently get with transconductance amplifiers or FETs. The LDR should be ~1M in the dark, but almost anything will do. Some of the component values are quite carefully chosen. The input capacitor (15nF - made up of a 10 and a 4.7 if the 15 is unavailable) is chosen to give some frequency shaping, and the interstage capacitor prevents handling noise affecting the compression. Green LEDs are chosen because they most closely match the response of the LDR, but yellow works almost as well. Obviously, the LDR / LED combination should be facing each other, and must be in a light-tight enclosure. I've set up the board with pads for both 10nF and 4.7nF in parallel if you don't have a 15nF cap.
Here's a simple compressor design by Jon Patton (aka midwayfair) that's good for guitar and bass. In Jon's words: The Bearhug is a tonally transparent, ultra-quiet, tiny, and easy-to-build compressor. It occupies some middle ground between the ultra-subtle compressors like the Flatline/Afterlife and Orange Squeezer and the super squishy compressors like the Ross. For more info on the design, Jon goes into detail in this thread on DIYSB. I built this one last night and it's everything Jon says it is. Very subtle, and a little bit of volume boost if you want it. Here's a few pics of my build.
Here's and interesting 3-band EQ from HomeBrew Electronics. They say it's like adding a second channel to your amp, cleaning up a dirty signal with the level turned down. Think the opposite of an overdrive or distortion pedal. Should fit nicely in a 1590B or 125B. Schematic for reference.
I can't remember how many times I've been asked to do this one. I started laying it out ages ago, but got frustrated or interrupted and never went back to it. But here it is now, better late than never. The layout is for board mounted pots and it will fit in a 125B enclosure. Just couldn't seem to get it narrow enough for a 1590B. Schematic can be found here.
Switching it up this week and doing a Filter Friday. This one could be used for both synth and guitar/bass. It's a cool filter effect based around the LM13600/13700.
I thought I'd mix things up a little this week and post some synth circuits people might be interested in. To start things out, here's a modified version of the classic Atari Punk Console. This has a few additional potentiometers for more control and a more versatile version of this popular synth. In the layout below note that VR stands for variable resistor as the schematic I laid this out from didn't have names for each control (there are 6, labeled A through F). Pardon all the jumpers, 555s are uncooperative for single sided layouts. Haha

Here's a simple one that should fit nicely in a 1590a. EQD's take on the Electra Distortion circuit. Instead of having a pot coming off the end of the circuit, the volume is controlled by a pot coming off the emitter of the 2N3904. It's really more of a gain control than volume and if you wanted to, you could add a master volume control coming off the output. Who doesn't love more knobs, right?
Here the Univox SuperFuzz with the mods done by FSB member derringer. It replaces the stock tone switch with a pot, as well as a few other useful mods. Socket the 2 ceramic caps going from the base to collector on Q1 and Q6 and try some different values (I'm guessing in the 100pf to 500pf range). This one's a little on the wide side, so you'd be hard pressed to fit it in a 1590B, but it should fit quite nicely in a 1590BB.
