A complete kit for the BSIAB2 (Brown Sound In A Box 2), a General Guitar Gadgets exclusive. It's a very good "cranked Marshall™ amp" distortion, with an optional Contour control for extra tone shaping.
About the effect
The BSIAB2 was designed by Ed Guidry. It builds on the cascading-gain ideas in Jack Orman's AMZ MiniBooster, as refined by Aron Nelson and Doug Hammond. It's one of the best heavy Marshall™-style distortions we've heard, and it still sounds good with the drive turned down.
Tone Report said of the kit: "It is superb for summoning that vintage-Super-Lead-on-11 sound that defined early Van Halen records, but at a volume level that will not summon the cops to your door. It can do lighter smoothly overdriven sounds just as easily as it can do tight, hot-rodded saturation, and with the optional Contour control, the tone sculpting options are many and varied."
What you get
- All the parts and materials you need to build one, including the ready-to-solder PCB
- 3-Knob Version: the standard BSIAB2
- With Contour (4 Knob): adds the Contour control, which replaces R7 with a 5k6 resistor and a 100k pot for a wider tonal range
- Enclosure: a 125B, a smaller 1590B or a larger 1590BB, drilled for your chosen version, or No Enclosure to use your own. Data sheets: 125B (3 knob, 4 knob), 1590B (3 knob, 4 knob), 1590BB (3 knob, 4 knob)

This is my third kit from GGG, and they’re among the best. Excellent quality PCB and components like Wima caps and Fairchild JFETs. I certainly will be getting more to build in the future!
Awesome kit my first time dabbling with electronics may have put a couple transistors in backwards lol but I really enjoyed building the pedal and not joking about the transistors gotta buy a couple new ones right now as a matter of fact 🤪
So excited to build this pedal! Shipped quick & professionally.
Quick shipping, great product. Would buy from GGG again!
Perfect! Thank you!

Fast shipping, everything as described. Haven't built the pedal yet, but I'm looking forward to it!
Great kit, a few missing pieces thankfully I had extras on hand. It would be great if they updated the photos of the boards though some components I had received were wildly different looking than the ones pictured.
Fantastic seller, good communication and fast shipping. My favorite overdrive/distortion - hands down! The search is over.
Vert gold transaction and good pedal ! Gold job thanks

As described, nice kit, great seller! Shipped fast, NO issues. Thanks, GGG!!!!
Great pedal. Fast shipping
This pedal is sweet, if you're thinking of the wampler, or the mxr 5150, or any other "brown sound" effects, stop the search, do yourself a favour and just get one of these beauties, it even seems to be adding a bit of "variac starving the amp for power" type effect when engaged. This piece of kit is well made, well packaged and shipped to Canada so fast I would not hesitate to order another pre-made pedal from GGG again, after all they are made by the man himself.
Perfect!
Thank you JD!
great service
