Also, what amp or amps were you using before? Not sure of the price back in the very early 70's but they surely were not low priced compared to other amps. Did Hiwatt immediately become a major competitor in the bass power wars? Marshall? What else was in the shops besides SVT and V4 in this power range in that era? Thanks in advance! I recall as a 10 year old some of the Ampeg gear in 1969 here in the midwest (Kansas City area), mostly B15 and other 60's Ampeg guitar amps. I use to get Ampeg mixed up with Ampex for some reason as a curious kid in awe of the powerhouse amps LOL!
