Welcome to All Music Inc's Musicdungeon, you are looking at a great piece.
This is the 1980s Frey Valve Leadmaster Electric Guitar Amplifier Head.
The same amplifier was also sold as the RSD Studiomaster.
This amp head has a lot of features- Pull Bright, Pull Boost, Pull Graphic, and Pull I/Ps which reverses the inputs,
Dual 5881s and 5 12ax7s putting out about 40w allows you to go a little further with the volume to push the output tubes.
The gain channel here has an almost fuzz vibe, especially when pushed- in terms of bass response and clipping.
There is a true spring reverb onboard as well, which adds depth to cleans and tails to leads.
This amp is in very good overall condition as you can see in pics- typical marks from age and normal use.
The Channel 2 input is tight but works as it should, and the pots have a bit of static, sliders are not original.
Tested and works as it should.
This is your chance to get your hands on a great rare amplifier head from Frey USA.
Don't pass this by!
