Hello Effects Fans!

Yes, things are going a little slowly, but we're still cranking out new rack effects.  Today we announce our MOAB module, which compares to the Univox UniDrive UD-50, an early '70s boost effect used by Jimmy Page and probably others.  It is a huge 3-stage silicon boost that goes from clean-ish to really dirty, especially good for pushing the front end of a tube amp.  In March of 1971, it appeared in a Melody Maker ad, along with Jimmy Page, his Les Paul, and violin bow, and was described as producing "an electronic cello effect".  With its large rocker foot control, it looked like a wah pedal and was probably often mistakenly identified as a volume pedal when seen on stage.

Whether or not you need an electronic cello in your band, this is a great boost that can wipe out the first several rows of your audience when you crank it up.  Its big output and early release lead us to call it the "Mother Of All Boosts".  We aren't qualified to make any medical claims, but we've not had any virus problems here since we cranked this module up through a half-stack...

You can see the details about our MOAB at: MOAB.  Or look for it in the Boost Modules section under Products -> Modules -> Modules By Type.
