Vintage Simmons Drums (UK) Users Group

hi all, when i switched my LinnDrum on it gave away a spike in the 
electrics, SDSV's all modules sounded at the same time... next i 
started a pattern on LinnDrum and jammed along on the pads, then i 
noticed something was wrong. the snaredrum square waveforms had just 
about 60-70% of the volume but the click sounded that it should (same 
volume as before i started LinnDrum) also it feels like the bassdrum 
module have more power now, i run all modules separately out of 
course... this is not an new issue, i remember it happend last time i 
had SDSV lined up and back then i did not need to switch anything on, 
it just happend all by it self ;=( anyone have a clue ?
i will add a wav-file into files section so you ppl can listen or maybe 
drag it into a soundeditor to look at this strange fenomenon...
