I recently purchased an Ampeg SVT410HLF enclosure, which is 450 watts at 4 ohms. I am searching for an Ampeg head to match with it. I’m curious about your experiences. I play in several bands. The average venue is a small to medium sized bar or club. I play music that runs from The Stones, Grateful Dead all the way to Black Sabbath. The bands run in size from loud four piece rampaging metal to 7-10 member band with keys, loud guitars and horn. I play active and passive four string basses. I need both a clean and dirty tone. I have PA support on about half my gigs. I have another amp for smaller/quieter gigs, so that is covered. The first option is the Ampeg V4B. At 100 watts through the 410HLF, will I have enough volume? I’m concerned about gigs where there is no PA to do the heavy lifting. Is the amp one dimensional? It seems to do the dirty OD rock and roll bass thing very well. The second option is the SVT3pro. At 450 watts, I am still somewhat concerned about horsepower, but not as much. I understand that the 3pro does clean and overdriven tones well. With a solid state power amp, it seems like it would be easier to maintain. I guess another option might be the SVT7PRO. I understand that it has only one tube in the preamp and does not overdrive as well as the above amps. However, it has a 1000w solid state power amp (I think?). I guess I could get the overdrive from a pedal, but is 1000w “too much” for the cab? I have Hartke LH1000 with a similar layout and it has served me well... but I don’t think the 7pro is much different than the Hartke. So, your thoughts? Yes, cost is always a factor... but I will wait until I have saved the money to get what I want. An SVT-CL or other traditional SVT all tube head was ruled out due to cost and the extreme weight. I feel like I would need an 810 to full utilize those heads. I dont need that much amp. If I needed one for a one off gig, I’d just rent it. Thanks in advance.
