I haven't posted here in years.
In 2011, I quit gigging so I could take care of my aging parents (who have now passed) ...so my use of 100 watt guitar amps has all but disappeared.
Back in 2009(?), Pete modded my Blackface with two switches and a hot-rod upgrade. I paid him upfront $200 and told him "there is no rush, just get it sounding right".
Pete assured me the turnaround would be less than 6 weeks. Nearly 6 months later, I demanded he finish my module. I got it back a week later, but there was an audible loud *pop* when using one of the switches. The overall sound didn't seem any better or even different from before.
Upon telling Pete of my dissatisfaction, he offered to fix it. I didn't want to risk having the unit gone again for another undetermined period, so I declined. He also offered to send another unit with the same mods, but I had lost faith in him by this time. I did not ask for or receive a refund. Pete warned me NOT to badmouth him on this forum so I never posted about it, till now.
I contacted Jaded Faith on here and he agreed to fix it.
He did! Sounds great now! (Still like my hot-rodded DLX better though)

In Pete's defence, he was dealing with a lot of ship in his life at the time. However, I lost my respect for his opinion (his ear) when I read this quote he posted on Rig Talk:
"Used a Kemper for nearly 3 years live, haven't missed a tube amp for performing since".
No wonder he was so mediocre or hit & miss at modding.
Don't get me wrong, modeling preamps are great in the studio. I have several units.
