AMP MODE OVERVIEW

The AMP MODE circuit is based on a MOSFET transistor which is a very popular type of transistor to use for boost circuits because it has many “amp like” characteristics when it clips etc. There can be downsides to this circuit though.

Several very popular MOSFET boost circuits on the market have a very noticeable crackle when their boost knobs are rotated. We fixed this issue in the AMP MODE so it is perfectly silent when the boost knob is rotated and delivers nothing but a crushingly loud and harmonically rich boost!

Use the AMP MODE as a preamp for your overall signal, a boost to push an overdrive pedal even further into saturation, or as a post overdrive boost to clarify and push your guitar forward in the mix! The AMP MODE features 9-18V operation, true bypass switching and a tiny footprint featuring top mounted jacks!

TONE TIP!

"One of the most powerful things about the AMP MODE is how well it stacks with other pedals as well as it self! For years I have run two MOSFET boosts on my pedalboard with a Klon in between them. I used one of the boosts as an always on boost, and added a second boost when I wanted an overdriven rhythm tone. Finally when I wanted a saturated lead tone I would kick on the Klon and the two boosts along with the Klon would give me a super articulate and saturated lead tone." - Brad Jackson 






BOOST CONTROL

The single boost control sets the overall boost for the AMP MODE. The AMP MODE is a true boost in that when the boost control is fully counter-clockwise, it doesn't boost your signal, it instead acts as a unity gain buffer that emboldens your guitars signal to prevent against tonal loss when drive long cables etc.

DC INPUT

The AMP MODE can safely run from 9V-18V DC (center negative). Running it at 18V will give increased headroom and dynamic response. Do NOT exceed 18V!


     






    BYPASS SWITCH

    The BYPASS SWITCH is a mechanical true bypass switch.

      Excellent tray
      Color: Sand Brown, Size: 9.5in x 7.9in
      This is an exceptionally high-quality tray. The design was well thought out and it looks amazing. I keep it in my top dresser drawer to organize extra cards for my wallet, my watch, cufflinks, and other items. I can’t say enough about the high level of quality. It stays in place, has great storage and very reasonably priced I thought.

      Luxurious
      Color: Sand Brown, Size: 9.5in x 7.9in
      Firstly, I was very impressed by the packaging and attention to detail, from the box to the lovely wrapping. I purchased the brown and the tray is beautiful with the two-tone. I love the tree imprint on the inside. It looks very rich and the leather has a great feel to it. I also like that the logo was imprinted at the bottom/back. This would make a great gift. Great product!
