The Ampeg SVT-CL bass amplifier head is where you go for a truly vintage, classic bass tone. Power it on, give the tubes a moment to warm up, and you'll hear the sound you've heard on countless recordings and radio hits. The SVT-CL owes this legendary tone to its all-tube complement, featuring 11 tubes in all! The controls are straightforward and no nonsense. This baby is built for one thing: crafting a great bass sound.

300 Watts of All-Tube Awe

The mighty 300-watt output of the Ampeg SVT-CL comes from the six 6550 power tubes. This drives the sweet, sweet tone generated by the 2 x 12AX7s in the preamp section, and the 2 x 12AU7s and 1 x 12AX7 in the driver section.

3-Band EQ and Ultra Hi/Lo Boost

The front control panel gives you a Normal and a -15 dB input jack for this single-channel amp. Here you'll also find the Ultra Hi/Lo boost switch, along with Bass, Midrange, and Treble EQ knobs. A Standby switch at far right lets you cut the signal momentarily when needed. This amp is not about bells and whistles -- it's about consistently great sound.

Output Options

Via the rear panel, you'll be able to adjust the SVT-CL's Biasing controls, and select 2-ohm or 4-ohm output. You've also got a Preamp Out/Power Amp In and a Slave output here. The latter allows you to push the front end on another amp, or run direct into a PA or mixer. A single balanced XLR output is here as well. A Ground Lift switch helps you cut buzz if it arises.
