Fender Pro Jr (Little-ish Valve Amps)

DULLFACT: the Jacques pedals webpage used to do this, and I hankered after one of their delays for years before I twigged what was happening.

I just bought a Fender Pro Junior for Â£140 off ebay. Soo I'm going to see how I get on with that. It's not 6V6 but if I don't like it I can flip it without losing money.

Â£140!? what?

Yeah it was pick up only so only had a couple of bids. It's in Banbury so my Dad can pick it up for me this week. Looking forward to it arriving!

no, 'tis your browser.

but that '57 strat doesn't sound like something that would costs 10s of thousands...

Amazing value when you consider you can get a hand built amp to your spec with top quality parts cheaper than a mass produced Fender.

Got the Pro Jr yesterday. I've only had a little play on it so far and haven't had the chance to try it with a band yet but first impressions are good. Seems to get plenty loud before it breaks up which is nice. It's a bit buzzy but not mentally so and it's a great size.

If you decide to sell Pro Junior
Laney Cub 10 has two 6V6 10 inch speaker and costs like $200 for a used one. I can't compare to Fender 6V6 amps because I haven't played them, but the clean sound is very nice to my ears, has some vintage vibe in it, not Voxish at all. The stock speaker is the cheapest Celestion Tube 10 and there are a lot of recommendations from the owners to replace it with something better, but I don't want to mod mine. Cub's own overdrive is not great, but ok for me till the moment when sound starts to become really distorted - this amp despite the classic cleans has pretty modern style distortion that is closer to higain, to be honest that confuses me a little bit. I think it can do some Black Keys style stuff good, I'm not a fan so I don't use it such way.
Never played it with the drummer, my opinion is that it can compete with the drummer only when noticably overdiven or distorted. For homeuse this amp is too loud at the same time.
The amp is made in China, feels cheesy, but sounds good enough for the money. Has small transformers which I guess not the good thing and output for external cab which is the good thing. And it is lightweight, I think it is almost the only 10 watt amp on the market that equiped with two power tubes.
This review shows it really well

Basically size of output transformer decides your low-end capability for a given power. Energy is stored in the core as magnetic flux. Each cycle can transfer at maximum as much energy as the core will hold. Switching power supplies will transfer over 500W through a transformer only a few cm cube by oscillating at >20 kHz.

Above the lowest frequencies the amp can handle it's going to be limited by the power available through the mains transformer (which usaully means what size that lump of metal is to transfer power at mains frequency*) and what the valves can pass, but at the low end it's how much magnetic flux you can transfer each cycle and that depends on the amount of metal.

*Side note; theoretically Murricans can get more 20% power out of their mains transformers because they run at 60Hz instead of 50Hz, so there should be less sag and tighter bottoms in the USA.

Thank you for the detailed explanation. In general I thought the same, though never was really strong(interested) in the theory of magnetic fields, transformers, etc. and that's funny because I've spent 5 years in the unuversity studying them.
As the conclusion manufacturers in their attempt to lower the prices of the budget amps use small transformers and cheap details. Wanna great output and quality pay more

I did a demo of the Cub 12r a while back.

Good sounds

I love this amp, it's been so useful. The sound has a really nice focus, with quite a strong mid-range making it perfect for playing Jazz. I've used it to teach and in classes over the past week and have had no trouble carrying it around the city or taking it on the subway.

I haven't had the chance to gig with it yet but will be doing so next week!

Next time I pick up a tube amp, it's probably gonna be a Laney. I've been so impressed by demos and in-person; this has that same 'full' clean sound I loves. Sure it takes pedals beautifully too, much like the LC50 I've tried before.

Aye, I'm bit of a Laney fan, love my VC-15 absolute class wee amp.

I'm dreaming of vc30 112, looks like a perfect amp for me

Also nice but way too loud for my needs, would love a Lion heart one of the best amps I've tried.
