The Friedman JOSE 20 takes the legendary tone of the original 100-watt JOSE and shrinks it down into a 20-watt package built for home, studio, and stage. Developed by Dave Friedman alongside Marisol Arredondo, daughter of the amp-modding legend Jose Arredondo, the JOSE 20 Series captures the feel, dynamics, and harmonic richness that made the original a go-to amp for professional guitarists chasing serious high-gain tone. It's a faithful, modern take on one of rock's most influential amplifier voices.
A Tone Built on Rock History
Jose Arredondo hand-modified British amps for working musicians who needed more sustain, tighter low end, and a more responsive feel than stock circuits could offer. Those modifications quietly shaped the sound of high-gain rock for decades, and the JOSE 20 translates that legacy into a repeatable, reliable platform.
Internally Bridged Volume I & II: Recreates the classic channel-jumping trick players once pulled off with patch cables, blending bright attack with warm body for a rich harmonic base.
Plexi/Gain Switch: Adds a genuine extra gain stage, moving from classic Plexi grit into the aggressive saturation Jose's mods were known for.
Developed with Marisol Arredondo: Built in direct collaboration with Jose's daughter to preserve the authenticity of the original circuit's character.
Circuit Controls That Shape the Attitude
The JOSE 20 is no one-trick amp. Its controls reshape the amp's entire response instead of just adding volume, giving you a wide range of usable tones from a single channel.
Fat Switch: Adds low-end authority and punch without muddying up the articulation that makes this amp so responsive.
Three-Position Gain Style Switch: Repositions the master volume in the circuit and introduces diode clipping, covering everything from hot-rodded Plexi crunch to fluid, harmonically rich leads.
2 x EL84 Power Tubes & 4 x 12AX7 Preamp Tubes: A tube complement chosen for touch sensitivity and the dynamic feel that defines the Jose sound.
Built for Real-World Playing
Great tone doesn't mean much if it's impractical to use. The JOSE 20 is designed to deliver the full Jose experience at volumes that work for rehearsal rooms, stages, and home studios alike.
System Master Volume: Dial in saturation at bedroom-friendly volumes or full stage output without losing the amp's core character.
Transparent Series Effects Loop: Integrate time-based and modulation pedals cleanly, without coloring the tone you worked hard to dial in.
Head or 1x12 Combo with Celestion G12M-65 Creamback: Choose the format that fits your rig, with a speaker selected by Dave Friedman for its warm midrange and smooth top end.
The Jose 20
The JOSE 20 isn't an attempt to chase a vintage sound with modern shortcuts. It's a genuine continuation of Jose Arredondo's work, built with input from his own family and refined by Dave Friedman for players who want that history available in a practical, gig-ready format. Whether it's loaded into a pedalboard rig or run straight into a cab, the JOSE 20 delivers tone with a real pedigree behind it.
