PSA: New Harley Benton GPA-100

£70 from Thomann

The GPA-400 is fairly well regarded so this should hopefully be a worthy alternative to the lesser liked Thunder 99 (and cheaper too). 

Until this I'd been eyeing up a Hotone Loudster.

Looks interesting

I'm guessing it's a clone of the Seymour Duncan Power Stage amps.

I've found the GPA 400 to be awesome. Might give this a try as I don't need that much power!

Looks to be useful for what I'm trying to put together, a small power amp in a funky looking cab so I ca use my modelling preamp into it if I need to play in public.

Looks cheap at £70, half the price of the EHX 44 Magnum. proper kettle lead as well and not one of those noisy laptop style psu things.

Though I would need to be careful as it's 100w and my speaker is only 50w, d'oh

Very interested. 
Using a matrix GT at the moment but most the time it's overkill and full rack size is awkward 

joehindley103

@thecolourbox you'll have absolutely no issues with a 100w solid state power amp driving a 50w 8ohm speaker trust me.

@joehindley103 ;

would that be the same for my 100W 4ohm speaker and the 190watts that this thing belts out? 

joehindley103

@paulphoenix absolutely. Solid state power into a speaker is not 1:1. If anything typically you'll be looking for double solid-state power to the speaker rating. It's not the same as you would treat a valve power amp and speaker match up.

It is crazy how cheap they manage to make things.

that looks freaking awesome

As a GPA 400 user I feel I could deffo use this as a back up

monquixote

So who's going buy one and tell us if they are any good?

guitarmangler

£70! How do they make them so cheap! You could buy two and expect one to blow up a year and it’d still be cheaper than a Duncan power stage. I’ve got no gigs until July, or rehearsals anytime soon, but a small cab and couple of these might make a easy to move rig when I do.

Does the volume work backwards? Looks like 0dB on the right and the infinity symbol on the left. 

monquixote

It's minus infinity.

It's a scale relative to peak power.

Ah. Missed the minus sign.

I guess that'll be me then.... order placed with Thomann this morning. Check back in 4 weeks for an update. 

monquixote

Awesome!

Daiganzen

Thanks for taking one for the team

Can I ask what this means? Why is "no sound" minus infinity, and "effing loud" is "0db"?  Why not 1 - 10 or something sensible?

It'll be referring to signal attenuation .... But I agree, 0-10 would make more sense to most. 


...I'll wait till the ones that go to 11
