Matamp GTB (Green)

Single model, only manufactured by Bass Matamp decades, as always with Matamp it's handmade, custom (ordered by a dealer who Matamp kept in his own collection without even connected ... I am strong when I start mode harassment ^ ^).
All Tube Amplifier Head gave between 120 and 160 watts per Matamp.
An entry for passive bass, one for labor.
Sensitivity (low active)-Voice-Prevolume-Bass-Medium-Body-Treble-Volume

UTILIZATION

No documentation included with the amp but in this kind of products, do we really need?
This gives a great sound regardless of the setting but to refine it becomes a bit more complicated because some settings are "coupled" as Medium and body.

SOUNDS

I play with the stoner is the perfect amp for this style of music, pushing a little prévolume we get a big fat grain to the edge of distortion.
I have a matching 2x15 Matamp
I play it with a Rickenbacker 3001 of September 1976, a home bigmuff bass Electro Harmonix Overdrive Mazette (French brand) and a tremolo Mazette.

OVERALL OPINION

I use this amp for a year and a half apart handle more decorative than anything else and weight (over 25 kg for the head and over 40 for the body) I see no downside.
I have used many models before fall for this one but do not regret my choice.
Price level, the head + 2x15 "matching cost me the same price as the Orange AD200B head alone (in France) so no worries on that front.

It is the best amp I tried.
