Kevin375, 07.06.2013
Don't be put off by the high price for this small amp. The Gallien Krueger reputation is well deserved. I use this both for practicing in a small room, and for performing in medium sized venues. For live purposes, the included DI out or Line out (both present) are essential.
There are connections for hooking up to a cab/speaker if required.

Lovely smooth sound, both from a double bass, and an electric Music Man.
Only thing to be wary of, is that these amps are a bit toppy. Be prepared to turn the bass up, and the treble and mids down.. unless you like your trebles of course.
The size is great for getting in/out of gigs. No back breakers here!

Overall, I'd highly recommend it.

A Useful and Compact Amp With a Distinctive Control Layout.

Bob M., 06.04.2016
The Gallien Krueger MB150S-112 III is a classic combo, and this is my second one, I had an earlier version that was in regular use for well over 20 years.

It features a range of useful tools for the bassist, including tone filters, a compressor/limiter, bass cut etc..

This version, MB150S, does not have the Chorus effect and stereo XLR outputs, unlike the the MB150E.

One notable feature often overlooked is the input impedance of 1M Ohm, which makes it Piezo pickup friendly. This means that it works well with a Double Bass, having no need for an additional pre-amp or buffer. This may go a long way to explain why these amps have had such a long history with bass players who double Acoustic and Electric basses.

Not so good..

Gallien Kruger for reasons unknown, have the tone controls set the other way round, i.e. Treble to the left and bass to the right. This is ok if it?s your sole amp, but in poor light it can be a little confusing, I would prefer a standard layout with the controls better defined using colour and/or knob sizes etc.

It?s worth noting that the headphone amp can be noisy depending on the impedance of the headphones used. I returned my unit to Thomann as faulty but they tested it and found it to be working correctly. I changed the headphones to (I think) a higher impedance and this fixed the problem.

Overall this is a useful tool and has a wide range of uses, it works well when used with a GK 12MBX extension speaker, creating a ?mini stack?, and the 12MBX is so light that it can even be used (unplugged) as a speaker stand on very quiet gigs.

So a useful and compact amp with a distinctive control layout that may not suit everyone, but proven over years of use by jobbing pro?s and Jazz greats alike.
