after reading the good reports on TGP i went out and bought one of these lovely little pedals,mine is V1.initial impressions? great,however........try this. place a dirt box in front for sustain,then set controls on the CC as follows; REGEN 'bout 4 rpts,MIX 'bout 1/2 way(these two settings are less critical than the delay knob setting in the following experiment) DELAY 'bout 4 o'clock. play a short/quick note and "kill" the string immediately,listen carefully to the delayed repeats...DO YOU HEAR IT,YOU GOT IT? yep, a high pitched whistle/whine mixed in along with the notes.aaaaaaaaaaarrghhh BUMMER! FYI one o' clock on the delay knob = 'bout 440ms. anything above ABO3J489 on the serial # = V2. i'm trying to find out....does this only happen with V1? can you hear IT with the delay knob set to one o'clock,and the mix backed off a little? (i cant) and for those who understand the nature of analogue..is this typical? your observations/feedback will be greatly appreciated,thanks.john. ps. gear used. les paul/ocd/CC/nova nr1/amp.
