After 35 years playing mainly Trace Elliot and Eden amps, I recently decided to try an Ampeg I can carry. I bought an SVT-3 Pro. Here's the thing, it doesn't seem to have much volume at moderate controls settings. I've read that they're "underpowered" but with the EQ disengaged, Bass/Mid/Treble flat (all the way anticlockwise - there's no pot detent so I'm guessing this is 'flat', not 'cut'), Input gain and Master at 12 o'clock, the volume into a Hartke 8Ohm HL210, is less than bedroom-sufficient! Inputs sockets (incl. '74 Jazz bass) and leads all checked & good quality / low capacitance / short length. All Hi/Low/Mute switches disengaged of course. I'd have thought it'd at least be loud at these settings. Can anyone suggest what might be going on? Underpowered or not, 450W (or 275W at 8 Ohms) ought to give reasonable volume with gain & master settings at midday I'd have thought. With a 280W (200W into 8 Ohms) Trace Elliot, I'm used to barely being able to get past 9 o'clock before it's deafening. With the Ampeg at midday it should at least be..."a bit loud"...no? The sound is firm, steady & clean so it's not the tubes I don't think (do correct me). Is it that the SVT-3 Pro characteristically develops it's volume 'late' when the pots are way past 12noon? I'd have though it'd be loud and overdriving by then, rather than just "loudish". To obtain anything approaching usable in a group rehearsal situation, I need both Input gain and Master to be at 3 o'clock (and the band's not 'loud' nor playing particularly heavy music), even going into 4 Ohms. Anyone with extensive SVT-3 Pro experience have any tips or useful comments please? Many thanks.

I will certainly feel that 2kg saving and I need to take care with my back. I also don't use Class D amps generally - I have a TH-500 for when I absolutely can't take a Class A-B. Basically, given the Ampeg is 12kg, I don't want to add 5 more. If what I started exploring here doesn't exist (and it would appear it doesn't in a realistic sense) then so be it. Thanks for all the references all. This threat could be closed. Regards.

Nope! Only if they're around 5kg for a 2U or 3U

Carbon is definitely lighter than Aluminium, less than half in fact..... but I grant you the issue about latches etc., size benefit and cost (I have carbon cases for some of my instruments but the maker (Wiseman) doesn't do rack units). Nevertheless, there are plenty of 3U cases at 3.8kg so I'm just exploring to see if I can get anything like 2-2.5kg. I already unplug pre-power leads. I have a nice (slightly dated) carbon Pinarello FP3 here too - more than adequate for my needs - I'd never spend Dogma money... Regards

Thanks. Indeed it's an SVT3Pro I'm hauling, plus and SVP=CL pre-amp. 4.8kg Thon case is heavier than I was looking for. I'm sure there must be something out there lighter, I was hoping for much lighter (eg. carbon fibre). I know I'm sounding fussy...

Any other suggestions folks?

Thanks. Will do. This will just hold a 2U Ampeg head and 1U preamp.

Hi - what do we think the most compact and lightweight brand of rack units is please? I need one to hold a 15" depth head. Anything carbon fibre light out there? Thanks

Many thanks for your insight gentlemen. Regards

Question re the 12AX7 and 12AU7 tubes in these things. Ampeg told me they've used Sovtek, Ruby and more recently (in later SVT Pro models) JJ. Anyone have experience or comments with these brands of these tubes and recommend one over the others? Thanks

There's an effects send level knob, not sure if that's a blend. I'm guessing not but I've no idea (clearly...) By example, the amps are Trace SMX, Eden WT, Ampeg SVT and Aguilar TH & DB series. Not sure how to check if loops are line vs instrument voltage - I guess plugging stuff and observing output level will tell me (c.f. 'just try stuff' above). Thanks for both replies. All good info. Keep 'em coming.
