the blend knob on my VFB-2 is acting strangely. when i turn it all the way to the right [ 100% ] it cuts the volume down to an almost inaudible signal. to boost my signal back i have a guyatone BL-2 with the volume knob maxed and a chrome morley power wah set to the toe down position as it functions as a huge volume boost with the fuzz and wah disengaged. both are in the loop of the barge. i can barely hear anything unless i have both pedals boosted this way. the more i turn the knob to the left, the more i hear my clean signal, to full volume when set completely counter clockwise. my pedalboard in order: stingray 4 [fresh battery ] > korg tuner input on the VFB-2 SEND > ISP decimator guyatone BL2 EHX bass micro synth boss PS5 boss PS3 boss ODB3 watson superfuzz chrome morley PWF EHX small stone> RECEIVE on VFB2 output > akai headrush > powered by one spot. BMS, headrush, wah, bl-2 powered by separate adapters. rocktron hush rack unit [ set to allow plenty of signal through ]> svt classic > 810 + 215 my pedals sound fine and loud one their own, but not with the VFB-2. going to email barge as well. can anyone shed some light?
