Two-Rock Sensor

Two-Rock Sensor

Two-Rock says:

"In the world of two channel amplifiers, the Sensor brings Two-Rock’s classic cleans, mixes a tighter, more aggressive overdrive channel, and adds a fully buffered tube effects loop… the ultimate package for players who love effects."

Features

"For years Two-Rock has been developing and reinventing the two-channel style of amplifier. The latest incarnation replicates the great clean tones that Two-Rock has become known for, and adds a more modern and aggressive lead channel. This lead channel, which incorporates an adjustable, internal tone stack, is voiced similar to British-style amplifiers. The fully buffered, tube effects loop is a first for Two-Rock, incorporating a Send and Return control with a switch for Series or Parallel loop function. This allows the user more control over the amount of signal moving through the loop and returning back to the amp. A new feature, Expansion, adds an adjustable EQ bypass adding more gain to either channel. This feature bypasses the clean channel tone stack, or isolates the internal tone stack on the lead channel."

  • Dual channel clean and lead with cascading gain stages and independent masters
  • NEW Expansion control allows an adjustable EQ bypass to the clean channel or isolates the internal lead tone stack. This Expansion function increases the amount of gain on the front end. This function is foot switchable
  • Fully buffered tube effects loop with Send and Return controls and a switch for Series or Parallel loop function which allows users the ability to use more modern, time based effects
  • New medium sized chassis for head and combo. Newly developed Combo dimensions have increased the dynamics for a harmonically rich tone

Two-Rock Bi-Onyx

Two-Rock Bi-Onyx

Two-Rock says:

"Optimal versatility: Independent EQ’s and Two-Rock design engineering give you new flexibility and freedom to achieve precisely the tone you want in any performance environment and for any style of music."

Features

"A Two-Rock amp named the Onyx was the brand’s first to offer completely independent clean and lead controls on the front panel. Over time the Onyx built a strong word of mouth and became well known for its superior versatility.

"The Bi-Onyx modifies the original Onyx circuit and is built with the same concepts in mind. It reflects everything we learned in the design and build of the Onyx, and everything we heard from players who were demanding a simpler layout to give them more tonal control."

  • Dual channels have independent clean and lead sections including EQ, Gain, Master, Reverb, Contour - and our newest feature, the Volume Boost
  • The Volume Boost increases the volume without affecting the gain section; that is, without distorting or adding gain
  • The foot switch controls the channel selection and allows you to add the volume boost to each channel.
  • The front panel and foot switch LED’s match, to let you know which channel you’re on and whether the boost function is activated
  • The new output transformer was developed and engineered to deliver a tighter low end and a broader range of highs and mids
  • The new speaker output feature allows you to have multiple cabs in use at the same time
  • We decided to install EL34’s as the stock tube in this amp, but if you prefer 6L6’s… flip the toggle in the back, install your tubes, re-bias … and you’re good to go

Specs

  • Two Channel (Clean and Lead) with an independent set of controls for both channels
  • Stock EL34 or optional 6L6 via rear panel switch (re-bias needed on tube changes)
  • Precision power supply
  • Newly designed output transformer for tighter low end and a broader range of highs and mids
