This page shows a few pictures of our guitar amplifier project.
If you play through an external preamp / effectunit, you are in need of only power amplification and aren't in need of more preamps.
Our guitar amplifier accept a balanced line level dual channel (stereo) signal and will not colour the sound except for the response
in the speaker cabinet and the speakers themselves (A pair of JBL E120).
Actually, the amp was tested by the Swedish guitar legend Janne Schaffer!
We can do all kinds of custom built amplifiers or modifications. If you got an idea of something you
would like to realize, contact us and we can support you in development and building of the amp.
The amplifier will output 170Watts RMS per channel into 8 ohm loads in stereo configuration.
The frequency response is well beyond 10Hz - 30kHz. THD is about 0.02% (1kHz)
The amp operates in class AB and has a total supply filtering of 6 x 4700uF (28200uF)
The following pictures will give a detailed explanation of the unit.

Front view of the amp. The cabinet is made of plywood. There are handles on both sides and
wheels for easy transportation. No way to see this is a powered speaker cabinet!
Back view of the amp. Amplifier heatsinks to the right.
Combo input jacks accept both XLR and 1/4" plugs. The inputs are electrically balanced.
Speaker output jacks - used if the internal speakers aren't enough or you want to use 2pcs of 4x12" speaker cabinets.
To the left there's a panel with fuses, level attenuators and mode switches.
