Bluetone Ocean 2+2 Reverb is our newest 2,5 channel full tube amplifier containing a bunch of our innovations. It has a world class Bluetone Fried Eye based Marshallish crunch channel and Bluetone Odysseus based clean channel, which based on world famous Dumble ODS with our modifications.

Clean preamp channel

Clean-channel is very versatile consisting a Bright switch, Mid Boost switch, Rock-/Jazz-switch and an eq section with Treble, Middle and Bass controls to modify widely your guitar sound. Clean channel is extremely versatile producing a warm Fenderish clean sound, which can also be adjusted to create distortion to some extend.

Overdrive-stage consists Gain and Level controls, which help to create all possible distortion sounds one can imagine. Overdrive stage can be switched on and off with a foot switch. With clean channel, overdrivestage can produce any sounds from light crunch sounds to distorted lead sounds.

Crunch preamp channel

Crunch-channel is based on heavily modded Marshall-world. It contains Gain, Treble, Middle, Bass and Master-knobs and a Boost-switch, which adds more distortion. Moreover there are also Bite and Fat switches, which are helpful when tailoring different sounds. With all these possibilitites, this channel goes from shimmering cleans to heavily distorted EVH style lead sounds.

Spring reverb

Amplifier contains a spring reverb with individual control for each preamp channel. Reverb can be switched on with a led equipped footswitch.

Buffered effects loop

Amp also contains a buffered effects loop with send level. This loop can be used also as a clean boost, if there are not any effects connected.

Power amp

Power amp is equipped with two individual pairs of power tubes. They change automatically when preamp channels is changed. You can use all normal octal power tubes like 6V6GT, 6L6GC, 5881, EL34, KT66 etc. Tubes should be biased when changing them. It is very easy especially when using Bluetone Bias Rate meter. Output power depends on power tube model from 20 to 40 watts. All preamp stages and effect loop use 12AX7/ECC83 tubes. Power supply rectifier has been done with diodes.

You can have a built in OPC (Output Power Control), which is a variac type solution (adjusts tubes voltages and output power) as an extra feature. OPC does not alter power amp sound and power supply behaviour like VVR.

This amp is available as a head or a combo model. It can be covered with normal tolex, laquered tweed or with oiled hardwood cabinet.

Head version appr. 15 kg. Combo version appr. 20-25 kg depending on speaker elements.
