General

Marshall's SV20H Studio Vintage is a 20-watt tube guitar amplifier head that's based on the highly-desirable and costly 1959 Super Lead Plexi. It gives you the same soundd at a more modest volume and has three ECC83 preamp tubes and two EL34 power amp tubes. It also has four separate inputs so that you can mix the high treble and normal channels (or loudness 1 and 2) if you wish.

Flexi Plexi

In terms of style, the SV20H is very similar to the 1959 SLP, but more compact. The mojo from the original model has been maintained as well with a 3-band EQ along with controls for presence, the master volume and a standby switch. Incidentally, the standby switch doesn't just turn the amp head on and off, it allows you to select 20 watts or just 5 watts, which is great for practice sessions at home. There are five different speaker outputs that allow you to connect this amp head to additional 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.

Cet ampli est une tuerie, quelle palette de sonorités. Du coup je ne branche plus ma pédale d'overdrive tellement ça crunche naturellement.🤘🤘🤘. Attention sans atténuateur c'est très puissant pour jouer chez soi.
