1 Watt Mini Amp
Here's a nice little solid state amp for headphone use or a small 4Ω speaker. Good candidate for a bench top amp for testing purposes. You can board mount the pot and it will fit in a 1590A just fine.

MultiCab Sim
Got a request for this one, designed by Daniel Schwartz. Seems to be a pretty versatile cabinet simulator. Might be handy to throw this in the same box as the Mini Amp from earlier this week. More...

Baja AFD
Here's a unique overdrive design by Bajaman over on FSB. You can build it with either a buffered bypass or true bypass. If using true bypass, omit the 1k resistor below the lower TL062, and the 1uF cap...

Baja SLO
Here's another one from Bajaman. It's a modified version of his AFD, but tuned to sound like a Soldano amp high gain channel. There are enough differences to necessitate a new board. More info here on...

Vertex Steel String
Here's a relatively new effect from Vertex–the Steel String Clean Drive. It's supposed to sound like a Dumble amp and is 2 muamps going into a BMP tone stack. Schematic can be found here.More progress...

Jext Telez White Pedal

zVex '59 Sound
zVex's new '59 Sound looks to emulate an overdrive '59 Fender Bassman amp and is essentially a tweaked Box of Rock. I've left out the boost section (which is essentially a SHO after this circuit), but...

VooDoo Lab MicroVibe
Here's the Micro Vibe from VooDoo Lab—aka, welcome to jumper city. Always seems to happen with vibe circuits, but this one will fit in a 125B quite nicely. Pretty standard adpation of the old Univibe...

Lovepedal Jubilee
Here's Lovepedal's Jubilee–pretty close circuit-wise to the Purple Plexi and Black Magic. Should be a pretty quick build. Note, if it sounds too dark, replace the 47nF cap with a 4.7nF cap. Schematic...

Os Mutantes Fuzz
Got a request for this one and thought it'd be a good Fuzz Friday layout. It's got a fair amount of treble and grit on tap and should fit pretty easily in a 1590a. Schematic here.

Baja VH4
Another drive circuit from Bajaman. He's been on a tear lately! In his words...Here is my latest build based on the frequency response characteristics of the Diezel VH4 tube head channels 3 and 4, but...

MXR Commande Sustain
Here's one from MXR you probably haven't heard of before. It was apart of their Commande line of plastic boxed effects from the late 80s. They aren't highly regarded because of the plastic, but the...

Fender Eric Clapton Active Mid-Boost
Got a request for this one. It's the active midrange boost (of up to 25dB at around 500Hz) found in Fender's Eric Clapton signature Stratocaster. Ended up not board mounting the pots for a smaller...

Frantone Cream Puff
Happy Fuzz Friday, everyone! Got a few requests for this one. It's a bit like a fuzz in the way a Big Muff is a fuzz–bridges the gap between fuzz and distortion. And it's somewhat similar to a Big Muff...

Lovepedal Tchula
Another Electra variation from Lovepedal. It's described as a two-stage COT50... I guess the "stages" are the different ways to bias the transistor off the emitter. The stages are switchable via...

TC Electronic Integrated Preamp
Here's a loud one for you (I am not responsible for any blown speakers that may happen as a result of you building this thing! haha)! It's a popular preamp and used as a booster by the metal band...

Boss DS-1 with Keeley Ultra Mods
Got a request for the classic DS-1 with some Keeley mods and since my earlier DS-1 layout doesn't have board mounted pots, it seemed like a good idea. The flip-flop switching has been removed. Here's...

Demeter Fuzzulator
Here's an interesting opamp-based fuzz from Demeter for Fuzz Friday. I imagine other dual opamps can be used in place of the LF442, so socket and experiment. The trimmer in the original seems to be set...

CultureJam Shoot the Moon
Here's a great optical tremolo designed by CultureJam. Schematic can be found here. D1 is the external rate indicator and could be used as the on/off indicator as well. Just use part one pole of your...

Active Baxandall Network
Got a request for a Baxandall tone stack daughter board, (much like the Big Muff Tone Stack daughter board) and thought it was a great idea as it's a great tone control. The schematic for this came...
