As for pedals used with the Herbert in general, I do. The amp takes pedals so well it's ridiculous.
Ch. 1- MXR Dyna Comp or Barber Tone Press
Ch. 1 BB Preamp #1- 50% Level, 50% Gain, Treble 10:00- Diezelized Dumble
Ch. 1 Xotic EP Booster, used before or after BB- Diezelized Dumble on Crack
Ch. 2- BB Preamp #2- Full Clean Boost
Ch. 2- BB Preamp #3- Full Clean Boost, Gain at 8:30- Think Eric Johnson
Ch. 2- DOD YJM 308- Flutey, Fluid with a little quack
Ch. 2+- EP Booster- Great for a bit of a kick or volume
Ch. 2+ BB Preamp #2- Full Clean Boost- Searing and Wild
Granted I use low output pickups and 40% less gain than 90% of Herbert users the amp itself
has quite a few sweet spots on it's own where the treble, mids and bass all align for tonal bliss.
Do I have to use pedals, no. I do because I can and I like what I hear. Users choice, the Herbert is incredible to begin with.
It is fun to use OD's to paint different overtones and sometimes compensate for inherent faults in certain guitars.
And yes, I have three BB Preamps.....
