Product Description
Dave Friedman knows a thing or two about modding amps. He’s earned a reputation as one of the most passionate guitar amp designers in recent years. Yet Friedman, like many of his peers, owes a thing or two to the late amp legend José Arredondo, an elusive yet prolific technician responsible for some of the greatest gain & amp mods in amplification lore.
To commemorate Arredondo’s profound impact, Friedman teamed up with his family to distil the essence of his most popular mods into a single 100w amp head!
José Arredondo: the ‘amp wiz’ responsible for rock & metal’s greatest tones
Widely considered an amp modification OG, José Arredondo made a name for himself working on amps for the rock & metal elite in the 80s and beyond. James Hetfield, Steve Vai, Eddie Van Halen – a real who’s who.
As an amp technician, he earned his stripes working for everyone from Vox to Ampeg, eventually starting up his own amp repair & modification workshop. Dave Friedman considers Arredondo’s subsequent mods to be precursors to many modern Marshall-inspired amps – including Friedman themselves.
For Dave, Arredondo was more than a mysterious figure tweaking amps for A-list guitarists – he was a personal acquaintance. He recalls getting his own amp modded at Arredondo’s workshop: “I had the pleasure of having an amplifier modified when I was about 18 years at his house, here in Sherman Oaks at the time. His shop was there, all the amps everywhere, a striped Eddie Van Halen on the wall – you had to move sideways through all the rubble! He was awesome.”
The Friedman Jose amp – what we know so far
Dave has worked on over 100 Jose-modded amps over the years, so he knows them inside out. Who better then to build an amp to commemorate the legend, complete with the blessing of his family? Here’s what we know about the Friedman Jose amp so far:
- At its core, it’s a 4-input EL34 powered 100 Watt Marshall-style head
- Multiple versions of Arredondo’s mod in a single head, based on his favourites from the 1968-75 era
- Two different style presence circuits: N presence (more mid-focused character) and V presence (vintage Marshall, very bright)
- Improved master volume switching: pre-EQ master volume with clipping diodes (later popularised by Cameron, Fortin etc.)
- Bypassable FX loop
