I also think it's not a really loud amp. Though I could keep up with one loud guitar and a loud drummer playing Stonerrock. But the master is quite on max, the gain is also wide open and I played it on my Ampeg fridge, I liked that sound, but far from clean. I don't own any other 100w tube amp to compare. Usually for smaller gigs with pa I have to turn down my volume quite a bit, compared to rehearsal settings, so that amp would make a perfect compagnon for small gigs.So I just found this thread after buying a Traynor YBA-100 and being seriously underwhelmed.
For context, I currently have an Ampeg V4-B that I love but don’t like lugging around so much. Having said that, it’s a killer amp with great tone and PLENTY of power. I also have an Ashdown ABM 600 and an Orange Terrorbass 500.
The Traynor is barely loud enough to play with my rock band (loud drummer and 1 guitarist). Whereas the Ampeg could bury them! This has me thinking that the 100 Watts rating is off.
My Ampeg has 4 of the JJ 6L6GC power tubes so I replaced the stock Chinese Ruby 6L6’s in my Traynor but there’s not a huge difference in volume or tone.
Wondering if anyone here has any insight or thoughts etc...
Coming from a V4-B and now the owner of a YBA100 I tend to agree with you. There's no way the YBA can keep up with a loud drummer, and I use a Berg NXT212 that is 104db SPL. The SVT 212AV (99db) with the V4-B was louder in my opinion. Sad to admit. But hey, it's 22 lbs, half the weight and size of the Ampeg. The YBA does have its place for low volume gigs, nice creamy tone there. Just don't play with Bam Bam.
I owned two V4B and two SVT in the past so I know about carrying boat anchors, maybe 100 w. is not enough for your duty, if you like the tone of the yba100 but find it not loud enough the yba300 could fill the bill and is easier to carry than a V4B.
Is it the original V4B or the reissue?Honestly, I may sell the Traynor or only use it for recording. The Ashdown CRUSHES and no volume issues. I was just really surprised that the V4B which has the same number of power tubes absolutely destroys the Traynor in volume and tone. I was hopeful for a V4B solution in a much lighter box.

The one thing I like more than the overpriced tour merch when I see my favourite bands is feeling like I'm going to poopie out my intestinal lining after the gig because they decided to play "Volume Wars" with their 800+ watt amps in a medium sized venue.View attachment 4056365
I love this amp. For those who are crying about it not being loud enough, you are trying to rock well beyond your means. If you are playing with a very loud band, y'all need to work on your dynamics. No reasonable person needs a dimed SVT... These amps are for arenas. If you aren't playing regularly in venues that have sound reinforcement, the answer is not a bigger louder amp- this is the most amateur move possible. It is hilarious to go see a bar band with a 500 watt mini PA and no drum mics when their guitarist and bassist have gear like they are on world tour. Lolz.

No need to get confrontational. We’re trying to have an adult conversation here, that’s all and if we happen to mention that it won’t keep up with a loud drummer who pounds the hell out of the kit, then we are just being objective. I think we would all, well most of us anyway, prefer NOT to play with that drummer, but sometimes we find ourselves in that situation. No one is crying here, Slick. No need to start with the insults.
Hey @GrapeBass - Any word on the tube pairing on the YBA-100? Is it inners and outers or left and right or ???
Good -- that's what I thought. I was gaslighting myself after the left/right comments earlier.Not trying to overstep here because I’m not Grapebass but yes inners outers etc

I wouldn't really compare my SVTII nonpro vs. my YBA-100, but I do:It's like... do you play an instrument or are you trying to convince people about the size of your penis by amassing audio equipment?

So, to put this in the broader context, and with reference to the circuit diagram, the pairs are left-side and right-side, NOT inners and outers.Thank you for pointing this out. I have reviewed the Block Diagram with the designer and found the current diagram needs to be revised. I've submitted the revised Owner's Manual and Service Manual to our website, hopefully it will be up shortly.
Looking from the rear of the unit, the power tube pairs are
V7/V6 • V2/V1
I hope this helps
Thanks for Shopping Y-Mart

edit: with this in mind, and with @GrapeBass' approval, I'd ask the mods to clean up this thread, so that it's clear to people what pairs with what![]()
