I wasn't sure if I should have posted in the old Hudson sidecar thread.
In 2024 Hudson Electronics introduced the "Motorcycle" as a limited edition:
"The Motorcycle is a modified version of our Sidecar overdrive pedal – our take on the soft clipping overdrive circuit with the added versatility of a powerful two band EQ which draws inspiration from a vintage recording console."
I have built many pedals, but I have never drawn a schematic before. I did my best to identify all the parts and the differences between the sidecar and motorcycle. Would someone be willing to help me draw a schematic and vero board?
This is what I found out so far:
- Hudson Sidecar vs Motorcycle: Differences
The gain and clipping section are completely different:
IC: OPA2134PA instead of LM4562 (not a big difference as both are hifi opamps)
Q1 (big change): Germanium Transistor instead of a BC549C
D1: LED for both
D2: looks like a 4005 instead of a 4148 (got that from the fulldrive I guess)
D3: nothing (Germanium Diode before)
Instead he uses the TY-250p for clipping.
Also he changed some pot values.

"The Motorcycle has been tuned to give more distortion in the lower frequencies and the EQ a different response. It also adds a transformer at the end of the signal chain to soften the attack and generate a subtle layer of saturation to the signal."
What can you make of this?
