Made of 500 in the second half of the 80's, all-tube 15W combo with integrated fixed attenuator 1 or 2W to plug the speaker into the headphone jack to play at night.

Made in '89, 4 knobs (gain, treble, mid (in fact acting as a second "gain", a feature of the model), bass, master volume), line-out jack and XLR. A single channel.

The only fitted with two 6L6 Marshall home. Two 12AX7.


Great and small ribs for all situations.


With 15W output and a real little monster, aimed at the studio at the base but is very, very strong and sends plenty to play for a big fat public. The clean is very clean (thanks to 6L6), and saturation is identical with very little close to a JCM 800 (series to which it belongs). It really can play everything with, without going into the extreme metal of course. From blues to very large rock / hardcore / punk etc..

With the release attenuated (1 to 2W) through the connection of the speaker on the headphone jack, there is still plenty of volume when everything is cranked to play in a bar. Can play at a very low volume but keeping all the heat lamps. The rendering is simply excellent.


Despite the single channel, I can still discover new sounds after three years of play, thanks to 6L6 I think. I do not know how they managed at Marshall, but it's a monster multi-level sounds available.
