WEM Dominator Bass MK1

Valve bass amplifier

WEM Dominator Bass MK1 The WEM Dominator Bass MK1 bass amp was WEMs bass version of the Dominator MKIII tube amp, first available in 1972. Both were 15 watt amps, electronically identical, but the Bass had a 15" Celestion speaker (G15M, 55 Hz, 16 ohms), as used by Marshall and other British amp manufacturers.

The valves are 3 x 12AX7 preamp, and 2 x EL84 power tubes, perfect for an overdriven sound at low volumes. Despite the intended bass use, this may be more widely used as guitar amplifiers. All the same, it is a nice bass amp for a grittier retro bass sound. Check out the sound clips below.

Although probably not powerful enough for gigging with louder bands, the WEM Dominator is a fine recording amp; famously durable, and easy to find in working order at a reasonable price.

This brings back some memories. Great dirty bass sound coming from that WEM amp. I had a friend (now sadly departed) who used this bass model for lead guitar and it sounded wonderful. It was definately a great all-round guitar and bass amp, and solid as a rock. Not so good for cleaner sounds, but for rocking out...

I have a WEM Dominator Bass Mark 1 and it is a great guitar amp. As a bass amp the Celestion G15M flaps a little with high output modern pickups but gives a nice vintage sound with my old Hofner Senator bass. As a guitar am it is quite amazing with a gorgeous break up from 50% volume. The speaker is a key part of the sound as it is in effect a 15" version of the Celestion Greenback. Its a shame Celestion dont still make them. The amp is a little more noisy than modern amps but I can live with that for the great sounds.
