Everything Didier makes is wonderful. There's other good options to choose from but if you like the size, power and price of the GSS then you can go for it with no reservations.

Straight Ahead power amp. The guy who makes them is based in New York. Small, powerful and transparent, plus very reasonably priced if you're in the US.

South west France I think, not NYC?

I'm talking about the Straight Ahead amp, not the GSS. Makes sense to look at US power amps if the OP lives there.

I recently bought a Baby Sumo. It’s fab. Small, light & powerful. Works a treat with my HX Stomp. I highly recommend these amps.

I would have gone for the more powerful Sumo but the whole point of me getting one was to be able to take it on public transport when I gig in central London at venues where a cab is supplied, so the lighter Baby Sumo made more sense for me. I use it to power a whole range of house cabs - 8x10s, 4x10s, 1x15s and my Berg HD112.

Sensible advice.

Thread resurrection alert!

I am looking to get a Baby Sumo to use with my HX stomp.

Is the baby Sumo small enough to fit in a gigbag pocket with the HX stomp and cables?

As small and portable as it is, I'd say it wouldn't fit in a gig bag pocket. It's 13 x 8 x 20cm and weighs 1.5Kg.

When I travel light to gigs I have a small backpack for my Sumo & leads, a bass in a gig bag in one hand, and my Metro16 Stomp board in a soft case in the other hand. Easy. If I'm driving it's the same, just with my cab too.

It's not a Pascal module in the Sumo, but a proprietary one made by Didier Elchardus, the guy behind GSS. I've owned the Sumo coupled to a Warwick JH PR40 Hellborg preamp and an Audiokinesis 18134 cabinet and and it's really powerful and defined. I've also owned the little combo 06B400 running on a lithium battery and it was also great sounding. I'm now using an FRFR 12+6 with tweeter (12 kilos for 500 Watts) coupled to a MarkBass Alain Caron Ground Stereo Pre pedal preamp. It's just amazing how good and transparent it sounds.

Go on, you won't be disappointed by GSS products and Didier is always ready to help.

I've got a 06B400 6.5" combo too, it's great. I'll probably splash for one of their 12" cabs next year.

I have a baby Sumo, and it is a great amp. Sound is great, loud, and background hiss is very low.

I also read somewhere that GSS uses a modified Pascal module. It is very difficult to develop your own Class D amp, certainly for a one-man company like GSS. Most of the bigger amp manufacturers use 3rd party ClassD power module from ICE.

On the german bassic.de forum there are some photos of the internals of the SUMO, and the PCB has the same kind of layout as the Pascal Modules:

If that helps, here's what Didier answered when I asked about the module as, to me too, it was very close to a Pascal module. It's in French as it's his mother tongue.

 

Need to remove the email address first...

It’d fit in my mono tick though... 🤔 

... I need to get back to work to stop me browsing the internet all day looking at bass stuff to buy 🤦‍♂️

Not that I need one, but does anyone know of any small form factor units that are stereo? (Other than being forced to buy two monoblocs)

Carvin have a stereo pedal-sized power amp coming out, but at 50W per side it's probably more guitar territory than bass.

Oooh! Very interesting! Thank you!

Currently reduced from $289 to $199.


I love spending other people's money... 😉

Edit: Hmmmmm, I've just seen it suggested that the Carvin is identical to this Harley Benton: https://www.thomann.de/gb/harley_benton_custom_line_thunder_99.htm  🤔

Edited by MartinB
Those pedals look awfully similar

Worth noting that the Harley Benton is rated at 2x50w into 4 ohms, whilst the GSS is 2x50w into 8 ohms. Carvin is also 2x50w into 8 ohms, but are they still in existence? I thought they went under last year.
