Thats weird for me to hear because I was thinking the treble on the Tone Pumped Euro 6 I just acquired sounds like it's voiced much higher than the OBP-1'd Euro4 and Legend 6 I'm sending to OneMoreRobot. Hmmm.....lawls.
Glad phat's legend found a home! I was very tempted, but I dont like the way the treble control on OBP preamps sound (kinda thin, really high frequency treble), compared to on a tonepump or spector 9V tone control.
I run the Euro4's OBP-1's treble and bass at about 40% with the EMG PJ's.
To run the EMG DC'd Euro 6 LX at about the same tone level I have to run the (old style, no trim) Tone Pump at about 10-15% on both treble and bass.
