Wavelength Audio, ltd. News Page.

Welcome to the new site for Wavelength Audio, ltd. Guitar Engines website.

So we support the Rock by the Sea foundation and pledge all our charity to them. Soon we will be auctioning off the Ed Robertson prototype amplifier that was used for their tours for the last 5 years. Yes it still works and if you want to hear some of it, listen to the Barenaked Ladies album Live at Red Rocks.


Signed by all the Barenaked Ladies and also from last summers tour Hootie and the Blowfish. Stay tuned to Rock by the Sea for more information.

NAMM 2019 I was talking to the great people at Preston Thompson and Collings about the show. It’s been awhile since we have done NAMM but I always remember how loud and almost impossible the sound was in the venue. So I came up with the Guitar Noggin. It’s a full guitar headphone amplifier with DI output. This is everything you would expect from me with crazy parts and custom transformers. The Preston Thompson group used it at NAMM to show off their new line of model T electric guitars.


This has a volume, tone and master control with a custom Headphone output transformer with a High and Low switch on the read as well as an XLR for the optional DI transformer.

Collings had a huge booth at the show so they sent theirs back and it’s up on Reverb if you are interested.

Isolation Cabinets: I offer two isolation cabinets now a large 12” cabinet that fits in a rollable ATA case and a new more portable (38 pounds) 10” model check out the product page for the details.


Here’s Ed Robertson of Barenaked Ladies with the two of the large ISO cabinets and the original prototype for his Bucket of Iron custom amplifier. The Bucket of Iron amplifier is a push pull 6V6 amp using our MPC (Magnetic Phase Coupling) technology which means 100% accurate push pull all the time. Plus it gives the amp more headroom.


Quark head, the new Quark with Tone Bank is available in the minor (5W-6V6) and the major (8W-7591A). I have a couple of prototype cabinets for combo’s for these but I think POYP is going to be my standard low wattage combo.

POYP (Piss off your Parents), I am a big fan of the Rock Boat. We go every year and as you know I make all the amplifiers and isolation cabinets for Ed Robertson of Barenaked Ladies. I talked to Ed on the 2018 Rock Boat and he mentioned his son Lyle was going to Berklee College of Music in the fall. During the Rock Boat adventure I ran into Lyle and Arden and was behind them talking about the boat. The POYP design literally popped into my head. As it is a crime to work on the boat I grabbed an IPA on the back deck, a sheet of paper and a pen and wrote the design down. Yes I was shamed by fellow Rock Boaters on Facebook but it was worth it this design is perfect combo for anyone looking for great tone and playability. Available with DI output option, Headphone option, 9V stomp box linear power and drivers (10” only: Warehouse G10A Alnico, Warehouse Veteran, Celestion Green Back 10 or Celestion Tube 10).
