the t.amp PM40C

Bought this on a whim to try as a backup guitar amp, the plan was to use this and a Joyo British Sound pedal just in case my main amp died during a gig. It really does sound good, and I've used it at gigs even when my main amp was working fine ;). For the money it really is an excellent alternative to carrying a big second amp to gigs.

It obviously isn't the loudest amp in the world but it's enough to get over a drummer in a pub rock band. Thomann do a louder 1u rack amp which quite probably would be a snic improvement, but I chose this mainly for the size, it fits in a gig bag, and weighs very little.

Although this little guy generates only 40Watts at 8 ohm,Class D type amplification,it does job well cpmpared to brand power amps designed
for use with modellers prevails in these days. Transparent with such little
distortion when cranked up the volume,it's worth to match with FR speakers.
In fact,suspicious questions crop up to me whrn it arrived. With an usual
test in combination with my Kemper as well as Axe-Fx2 original version,it
has come to a conclusion that no particular diferences are found at bed room
volume levels. Not so sure when fully cranked up at full volume whether it
confront such a high end amplifiers in MOSFET circuits. Well,though its
circuittry are in the domain of monitor speaker output generation level,it
really does worth the price with consistence sound quality. Yes,it does.

Mine drives 2 big 25 watt treble horns, the horns are 8 ohms each, connected parallel to use the full 50 Watts available from the TM40c if needed. My mid range 10"ers are 300 Watts, my 18" bass is 800 Watts, all sound pretty well balanced when pushed hard. My active crossover does the frequency separation magic. I'm a "mono" solo artist and like the ability of being heard if I feel the need. The TM40c fits the bill perfectly turning my horns into an "active" unit, I like the 1/4 jack or XLR input, it makes this little amp very adaptable as I still use some older 1/4" jack only gear. Perfect for me, plus the almost unconditional Thomann services.

I got this to convert a small stage monitor from passive to active. It does that OK for low level gigs but would need more power for bigger jobs. Overall this is a good little amplifier but it could be even better. Version 2 needs a few improvements:
(1) Longer output wires : 40mm isn't enough! 200mm would be nice
(2) An IEC power outlet to allow multiple units to be daisy-chained
(3) More power! 100W into 8 ohms would be good
(4) A more secure & study volume knob. The tiny brittle plastic knob on a plastic shaft pot doesn't inspire confidence or predict longevity. A larger knob on a metal shaft pot would be better.

Just attached a speaker lead and plugged it into an old Vox 1x12" cab loaded with a 4ohm Celestion neo speaker, played an original 1976 Fender Telecaster, all sounds fantastic. Lovely to just hear the tone of the guitar, cab and speaker. No valves to burn out and no iffy guitar preamp pretending to deliver a signature tone or drive. Also great for bass guitar (tried with a Fender Jazz Special into 4ohm Fane Colossus). Guitar or bass will only deliver a sense of a loud 40 Watts with a pedal (or other device) boosting the instrument to (or close to) line level otherwise it is going to sound like a sweet 20 Watt (perfect for practice or recording) if you simply plug your guitar straight into the PM40C.

I installed this in a speaker cab to drive a 12" Celestion Greenback G12H and I'm (surprisingly) pleased with the sound, especially considering I'm comparing it with a valve amp, so I'd definitely recommend it - and very good value for the price too.
On the design side some have commented on the volume knob position, and I'd change two things: firstly, as others have pointed out, the speaker lead wires are way too short, and probably should be terminated in a simple connection block anyway; secondly a very small thing but two of the mounting holes are badly positioned making screwdriver access tricky, especially in a confined space like inside a cab...that's picky btw!
That's it - good stuff Thomann, thanks for making kit like this available and at a really good price too.
