ENGL 3
Another ENGL amp emulator and another schematic from a russian DIY forum using both J FETs and MOSFETs. It is worth socketing the diodes at the MOSFET transistors since these only add a bit compression to the distortion.
Amp Emulator
Krank SK – Krankenstein Amp Emulator
A J-FET / MOSFET amp emulator of Krank Krankenstein. Very interesing transistor setup with MOSFET and silicon diodes in some of the gain stages. Schematic specifies KP303s for the J FETS but western analouges is J201 and 2N5457/58. Managed to keep it reasonable small so the brave one could try to fit this 6 knobber … Read more
Catalinbread Dirty Little Secret RED
Same mods as with DLS V3 (external gain and tone switches). Schematic is avaiable HERE
Catalinbread Dirty Little Secret V3
Slightly modified with the internal DIP switches moved to the outside and splitted into two DPDT switches. One is for gain and one is for the tonestack (Super Bass and Super Lead modes). Schematic is avaiable HERE
Catalinbread Dirty Little Secret V2
Recently traced by Aion Electronics. Schematic is avaiable HERE.
BAJA EVH 5150 Overdrive w. MTKs gain mods
MTK have done some great work on the BAJA 5150 OD circuit to squeeze more gain out of it. And a short video clip. stock settings in the first 20 seconds, after that, the modded settings.
Mad Professor Simble
This is been traced for a few weeks now over on FSB and I’ve meant to lay it out since then, but just now getting around to it. If you don’t know, it’s an amp-in-a-box type trying to emulate a Dumble amp. Apparently it sounds very good with smaller amps. Should fit nicely in a … Read more
