Another fail!
Here is a UBE Screamer with blend knob. I left a resistor out of the mixer and mixed up the Blend and Gain labels, double fail! As long as I’m going to screw things up I like to go all…

UBE Screamer v2
I made an update to the RunOffGroove UBE Screamer from a suggestion in their notes. This version adds a mix control the blends some of the original signal with the distorted signal. The original uses Rx to set a fixed…
1981 Inventions DRV clone.
Here’s a PedalPCB Informant. This is mostly the Rat circuit with a few changes. The biggest change is the addition of a charge pump. The charge pump provides a +9 and -9 volts power for the circuit to run off.…
UBE Screamer 1.1.1 build
Built and tested the new version of the UBE Screamer PCB. Everything is working! Sounds great. This is a good alternative to the standard TS-808 and other overdrives if you’re looking for something a little different. Does great low gain…
UBE Screamer 1.1.1
This is an update of the UBE Screamer board. Same circuit just revised. I had these boards fabricated at PCBWay.com. The quality is very great! The UBE Screamer is a very interesting take on the Ibanez Tube Screamer by RunOffGroove.com.…
RunOffGroove UBE Screamer
This is another great RunOffGroove project. It’s a unique twist on the classic Ibanez Tube Screamer. The UBE Screamer replaces the op-amps and transistor stages in the Tube Screamer circuit with inverters from a 4049UBE hex inverter. I built this…
Work in progress
I always get into something for a while, then need to take a break. There are a few hobbies I always seem to come back to. Pedal making is one of these! I dug out a few of the boards…
Sunday Drive (BJFE Honey Bee Drive clone)
this is one of my favorite overdrives. With a dark smooth tone, it’s really an overdrive, rather than a low gain distortion. It really never goes into hard clipping which gives it an expressive dynamic range. I built this from…
Vulcan by Joe Davisson
Great overdrive/distortion with good dynamics and clarity cleans up well with volume knob. You can buy this one at my Reverb Shop. Or, build your own! Order PCBs from OSH Park and follow the build doc. Vulcan On OSH Park…
UBE Screamer by RunOffGroove
This UBE Screamer by RunOffGroove.com is a unique twist on the venerable Ibanez Tube Screamer TS-808. It replaces the op-amps and transistor stages with a single hex inverter using an inverter in place of each op-amp and transistor. This has…
Vulcan V1.2
Here’s a Vulcan V1.2 circuit it adds reverse polarity protection, and ground pads for input and output jacks. These are available on OSH Park. Order some boards and follow the build guide to build your own Vulcan. Vulcan On OSH…
Vulcan v1.1 PCBs
Vulcan PCB. This is a great sounding overdrive by Joe Davisson.
