I just got an Avatar 45 which is fantastic but also fantastically loud. With the MV off and the bright channel at 3 (clean) its the same volume as my 20 watt 6v6 heritage victory on 8. I never put the victory over 6 at any gig so that gives you an idea of the volume the 45 puts out. I play mostly small bar gigs using small clean fender amps like a DR with pedals. I want to use the Avatar with the gain around 7 for a base crunch tone that I can roll down for clean and push with boosts and OD/ fuzz pedals for more gain or leads. The Avatar's PPI MV works well down to 3. Below 3 the tone suffers. So my idea was to use an attenuator in conjunction with the MV to get the volume where it needs to be for these small venues. I'm looking at the weber mini mass or the Phaez Brink 4:8 because I just spent $1500 on an amp & cab and I didnt want to spend more than $1000. I am not looking for advice on the best attenuator on the market. They all suck tone below a certain reduction level anyway. <$150 is my budget and I'll be sticking to it. The idea is get the MV up to 5 and use the attenuator sparingly to knock off 3-6db. I'm not looking for "bedroom" levels. The big question I have is whether an attenuator negatively effects how pedals work for pushing the amp. I have seen a few references in various threads that suggest attenuators ruin the pedal/amp interaction. Boost/OD/fuzz Pedals are a big part of how I will be using this amp. The other question is do I really need a 100w attenuator for a 50 watt amp? Would it be dangerous to use a 50 watt attenuator with a 45 watt amp?
