Brown Sound in a Box 2
Somehow I’ve not laid out this DIY classic, so here’s the BSIAB2. It’s a great distortion pedal designed by Ed Guidry and is probably a must for any of you EVH fans.
Overdrive
Catalinbread Hyperpak
Here’s an older design from Catalinbread (now discontinued). The Hyperpak is based around a CD4007UBE to generate a wide array of tones. Be sure to use the unbuffered version of 4007. Shouldn’t be too hard to fit into a 1590a like the originals.
Bartolini Tube-It
Came across a schematic for this awhile ago as it seemed interesting. It’s supposed to be a fairly rare overdrive pedal fetching up to $500. Here’s some information I found about it: The rare 1980s Bartolini tube-it Distortion Overdrive pedal made in Livermore, California, USA. Makes any amp sound like a Marshall. This may be the … Read more
Red Llama + BMP tone stack
I drew this up last month on a whim, built it and it actually sounds pretty good. It’s just a Red Llama with a Big Muff tone stack tacked on to the end. Ripe for tweaking to your own taste, especially with the values of the tone section. I changed the values to give boosted … Read more
Tube-Town Effects
Here is a serie of tube effect pedals by the German Tube-Town which were requested a while back. There aren’t videos available but you can find all infos, schematics and pcbs on their website here. (The Pepper Shredder has been discontinued but it’s supposed to be a tube distortion based on the Twin Valvecaster)
Electro-Harmonix OD Glove
Here’s the Glove from EHX’s nano series. Essentially, it’s an OCD with a switchable charge pump. On originals the voltage switch is internal, but external makes more sense to me, so wire that to your preference. Here’s the schematic for reference.
Black Cat OD-1
This one’s pretty simple, but is really versatile going from light overdrive to fuzz levels of gain. Originals use an OP275, but other dual op amps can be used (1458, 4558, TL072, etc.). It’s should be a nice fit in a 1590a.
Hudson Electronics Broadcast
Original info: The Broadcast is a transformer coupled, discrete Class-A germanium pre-amplifier based on the classic broadcast consoles of the 1960s. In the low-gain setting, the Broadcast can cover everything from sparkling clean boost through to transparent overdrive, all with a healthy dose of volume available to push your amp. The Broadcast features a specially selected Triad steel-core … Read more
Ibanez ST9 Super Tube Screamer
Here’s the Super Tube Screamer from Ibanez. It differs from a normal TS9 with the input buffer and the added Mids control. I’ve laid this out for board mounted pots with a 125B enclosure with top mounted jacks in mind. Here’s the schematic for reference.
Bogner La Grange
Original Info: The La Grange pedal is designed to emulate the famous British “Plexi” amplifiers from the mid 60’s. The wide variety of controls and switches, give you decades of legendary plexi tones, all the way up to the era of the modded amps from the late 80’s and throughout the 90’s. An independent boost … Read more
