Our Amped S-bass preamp revitalizes the harmonically rich sound and legendary performance of the Ampeg SVT. Get five frequency bands mid boost / cut rotary switch and an improved mid-frequency boost/cut frequencies slightly – 220Hz, 440Hz, 880Hz, 1k8Hz, and 3k5Hz – that gets as close as possible to octaves of “A 440 “.
The legendary Ampeg SVT is a bass guitar amplifier designed in 1969 to be a stand-alone amplifier or “head” as opposed to a “combo” unit comprising amp and speaker(s) in one cabinet. What made it a vital amp for bands playing in large venues was its prolific sounding and capability of 300 watts output at a time when most amplifiers couldn’t exceed 100 watts output.
The amp has been through many design changes over the years but is still in production today, maintaining its status as one of the greatest amps of all time. Now, you can have it in the shape of a pedal!
The original version uses one 1P8T rotary switch offering 5 different eq responses. However, this leaves 3 positions with no effect at all.
This was improved on version 1v1, where we replace the 1p8t for a 1p12t which you can configure through the washer for using only 5 positions.
