All-tube 50W amp head offering a vast range of tones, with a user-friendly bias section to swap tubes quickly and easily.

The Randall RT503H tube amp head from the RT series is an extremely flexible, all-tube amplifier head offering a range of tones from clean Country and Jazz to full Metal and Shred. Each amp features black chrome steel grill and control panel, spring reverb, and an effects loop.

In addition, the Randall tube amp head features a power tube bias section allowing you to bias the power tubes yourself, an easy and money-saving operation detailed in the instructions. This user-friendly bias section on the back allows the player to replace, bias & match the tubes themselves with just an inexpensive volt meter available at any electronics or home improvement store. The Randall RT503H amplifier head from the RT series uses 12AX7 preamp tubes and 6L6 power tubes that can be swapped out with EL34s for a more British vibe.

The Randall RT503H amp head features three discrete channels. Channel 1 is a Classic Clean, which allows you to go from sparkling tone to highly overdriven force. Channel 2 is a Classic Overdrive, bringing your tone from mild grit to full saturation. Channel 3 is a Modern Overdrive, which brings out full high-gain sound. The EQ controls include bass, middle, treble, and a bright switch on the clean channel, so you can pinpoint your ideal individual amplified guitar voice. The master controls on the Randall RT503H amp head include volume and reverb, for that full sound and depth. Series EFX loop, switch for rack or pedal compatibility, and an included 3-mode footswitch round out the package.

Comments about Randall RT Series RT503H 50W Tube Guitar Amp Head:

This is a well-rounded and flexible all-tube amp, with excellent clean and vintage distortion channels, but let's face it, this is a Randall. You are looking at this because you want to blow a hole in a brick wall, and look cool doing it right? Right. Well, let's just cut to the chase. The 3rd "Hi-gain" channel sounds amazing. Tons of gain, but it's not at all "fizzy". The closest I can come to describing the hi-gain sound would be the last few Exodus records. If that's the sound you're looking for, you will get it here without having to buy a single pedal to noise-up your signal path. The blue glow looks sweet as well. Right now, I'm just waiting to afford a 2nd one to run stereo :)

Comments about Randall RT Series RT503H 50W Tube Guitar Amp Head:

This amp is fantastic. the footswitch is wonderful, and all the channels sound absolutely great, but here's the catch, on its own. This amp has absolutely no midrange on either of the dirty channels. Even when maxing out the mids. this amp cannot cut though in a 3 piece band. I tried to, and the experience was awful. I hated to have to take this amp back due to such a stupid flaw, but randall is known for metal, and a lot of metal is scooped. I prefer a fat mid range for a nice bite. A guitar is a midrange instrument, so why would you even think of scooping the mids? Anyways, i tried using a boss ge-7 to solve the problem, but that didn't work, but I never tried it in the effects loop, so that might help, but my whole intention of buying a high gain tube amp was to have less pedals and a simpler rig, so that was out of the question. In the end, the Peavey XXX was a much better fit for me, but if you don't care about people hearing you, this amp is perfect.
