Standard 5150/6505 Mod Includes:

  • We remove the fuzzy/buzzy characteristics in favor or of gain that is more articulate/defined/clear
  • We tighten up the bottom end so it's rock solid and never loose/tubby/woofy
  • As make the clean channel cleaner/more airy/chimey/open sounding as well as warmer
  • The crunch channel is greatly improved as well
  • We convert the amp over to adjustable bias (normally $49.95 extra) based on the tubes type you want to use (6L6 or EL34)
  • We balance out all the frequencies so the amp is more even sounding over all as well as responsive
  • You can get more of a cranked tone at lower volumes as well as sustain
  • The amp will be able to cut through the mix a lot better both live as well as in the studio
  • Improve the harmonic structure so harmonics leap off from the fretboard with ease
  • The EQ section will be more flexible over all
  • You can get a cranked tone at lower volume levels (the clips on our site were recorded with the Master Volume on "1") the amp will also sound great at higher volumes as well
  • All features will still function the same and we do not add/remove any tubes nor do we drill any holes
  • We do not modify the FX-Loop or the switching system, only the preamp and the power amp
  • Add-On Controls: We are not able to add on any extra controls as there is no physical room inside the amp to make that happen
  • We can dial in the amp to your personal tastes if you so prefer
  • We charge a flat fee of $395.00 to mod the Peavey 5150 series and this includes the 5150 and the 5150 II heads. Combos are more in-depth as they are laid out differently and we basically have to disassemble the amp to mod it. The combos are $425.00 to modify.
  • TURN AROUND TIME: 2 business days!!
