maestro boomerang question

[bagudan]

Hi.
I ´ve made a boomerang from this layout. it´s working alright. But it seems to be distorting a bit. The soundsamples I´ve found were all very clean?
The distortion is more present with my middle or neck pickup, and especially in the heel-down position. I´ve tried different transistors for Q1 (bc109s,2n2222a´s,bc108´s) Even tried one with an hfe around 150. The distortion didn´t dissapear?
I used an inductor from a dunlop crybaby? I´m not shure if the inductor has alot to say, when it comes to gain and distortion?
Thanks

You might want to try increasing the 120 ohm resistor off the emitter of Q1. Tack solder a 1k pot in its place and tweak till the distortion disappears. Replace with a fixed resistor.

Here's what I ended up with after encountering distortion with the stock schematic.

thanks. i´ll give it a try right now

Worked like a charm. Settled for a 330 resistor. Thanks for the replies

I need to try this version sometime.
