General

Marshall's SC20H Studio Classic is a 20-watt tube guitar amp head based on the JCM800 2203. It gives you the same sounds as the model that was introduced in the 1980s and has been making mayhem ever since. The SC20H has three ECC83 tubes in the preamp and two EL34s in the power amp. That means you can get the same tones as the JCM800 2203, albeit at a lower volume. It's even possible to dial this amp head back to just 5 watts for practice sessions at home.

A modern classic

As you can tell from the control knobs on the SC20H, this model belongs to the Lead series. It has a 3-band EQ along with controls for presence as well as a preamp volume and a master volume. There are five different speaker outputs that allow you to connect this amp head to a variety of cabinets. There's also a DI out so that you can connect it directly to a mixer or a DAW, for instance. Finally, there's an FX loop on board too.

Wrote the following about Marshall SC20H Studio Classic JCM800 2203 tube guitar amplifier head, 20 W

I bought this amp to play at home and I'm very happy with it. It delivers the authentic JCM 800 tone in a smaller form factor and at lower volume levels. Having said that, you still need to turn it up quite high to get the best sounds out of it. The 5 watt mode only knocks off a few db's, so if you need to play this at bedroom levels, a high quality attenuator is a must! I'm using a Rivera RockCrusher which allows me to attenuate the volume down to whisper quiet levels with very minimal (if any) loss of tone. The high input gives you that classic crunch marshall tone, but you can boost or push this with pedals (BOSS SD-1 works great with this amp) to turn it into a metal monster. The low input can generate really nice clean tones and works as a great pedal platform, but if you crank the volume and gain you can take the tone into Plexi territory. Overall it's a very versatile amp and one I can see myself owning for a long time.

Bax Music offered the item for a really good price and shipped it from Europe in a timely fashion. The box was damaged (had a number of holes in the outside) when it arrived, but that's most likely due to the handling by one of the couriers involved. Thankfully, Marshall package their amps really well and there was plenty of protective materials inside to prevent damage to the amp inside. This is the second amp I have bought from Bax Music (the first one was delivered fine without the packaging being damaged) and I would use them again in future.
