The Tubedreamer mk.2 is a warm, rich and articulate 808-style overdrive built to cut through a mix without ever sounding congested or harsh. Its carefully tuned midrange, improved low-gain resolution and touch-sensitive response make every setting feel musical, from subtle edge-of-breakup push to saturated lead tones.

At its core is the legendary JRC4558D chip, paired with three-diode asymmetrical clipping for natural response to picking and fretting nuances. A new no-diode mode delivers a more open, dynamic and amp-like feel with extra headroom, while the dedicated HIGH GAIN footswitch turns the pedal into a flexible two-stage performance tool.

TubeDreamer details

Improved low-gain control
The mk.2 offers finer resolution at lower Gain settings, expanding the range of usable clean push and edge-of-breakup tones.

Two clipping voices

  • Asymmetrical mode uses three diodes for classic warmth, touch sensitivity and harmonic texture.
  • No-diode mode removes diode clipping for a more open, dynamic and amp-like response with greater headroom and clarity.

Footswitchable high gain
The dedicated HIGH GAIN footswitch activates an additional gain stage. Two internal trimmers set its output independently for asymmetrical and no-diode modes, allowing matched levels or a deliberate boost.

Controls
Level controls output, Tone adjusts tonal balance, Gain sets drive and the Clipping toggle selects asymmetrical or no-diode operation.

Programmable startup
The effect and HIGH GAIN stage can each power up on or off. Disconnect power, hold the relevant footswitch or footswitches, then reconnect power to save the desired combination.

Designed by musicians, for musicians.

From vintage-inspired classics to boundary-pushing analog designs, each JAM pedal is crafted with care to inspire your sound and spark your creativity.
Designed by musicians, for musicians.

JAM pedals began in 2005, when guitarist and sonic explorer Jannis Anastasakis set out to build pedals that didn’t just sound good, they sounded alive. What started as a one-man workshop in Athens has grown into a passionate team of builders, artists, and musicians who still make every pedal by hand, one at a time.
