Tubeworks Real Tube 903 Modded Tone Stacks
So as most of you guys know when I’m studying for exams I tend to do a bunch of layouts when taking breaks to keep my sanity. So since I did a layout for the Tubeworks 903 I thought to myself if it’s basically a tube pre-amp I thought why couldn’t the tone stack be … Read more
Tubeworks Real Tube 903
JohnK had made a layout for the 903 awhile ago, and since I did a layout for the 901 i thought I’d see if I could make a smaller layout for the 903 to make it easier to put this in a 1590BB with plenty of room. I took his switch wiring to make it … Read more

Well it does clean boost with the Gain set at minimum, flick on the Dirt switch and you get some nice diode clipping too. Turn up the Gain and you’e into overdrive territory with diode clipping, flick the Dirt switch … Read more
ZHBoost
Another submini tube based booster/overdrive pedal created by himister over at FSB, schematic. Make sure you are rated at least 25V due to the increased voltage from the rectifier. An additional mod you can do is replace the trimmer with a 250k pot so you can control the distortion produced by the tube on the … Read more
Frequency Central Red Star Drive
A real nice booster/overdrive that’s basically has a submini tube that replaced the transistor create by frequency central over at DIYSB, schematic. Make sure you are rated at least 25V due to the pedal running +12V. Version 1: Symmetrical Clipping Diodes Version 2: Asymmetrical Clipping Diodes
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.
