Seeking your real world class D amp head comparison and experience

Thanks for the responses so far. It’s prompted some research and a question.

Do all of the bass guitar ultra small class D amps use Bang & Olufsen’s ICE modules? Are we essentially dealing with the same power section in every unit and the differences are more in terms of Preamp voicing? Or are there some which use their own proprietary power sections?

To my knowledge, all but the Quilter Bass Block use the ICE. Pat made his own, cuz ...well, that's what he loves to do!

The only one that I had any issue with was the Carvin, which died twice due to problems unrelated to the power amp section. I threw that one in the trash rather than try to get it repaired a second time.

Maybe you can give me a little info? Quoting myself from a previous thread:

I've got a BX700 purchased new near the end of 16', and started having problems last year. I searched & read every thread/post on the problems associated with the BX series, and the immediate problem seemed to be a cheap 4-wire ribbon connector on the input jack. It would keep cutting out (kinda like the sound you hear when the battery in the bass fails) until I unplugged the cord from the bass, and quickly plug it back in - then it came back on for a few minutes till I had to do it again & again. After about 2 hours it would finally stay on. I took the top off, and pulled the connector off - the reseated it and that seemed to have fixed it. Fast forward to now, and it's started doing it again. I really liked this amp with the 3 EQ sections - can dial in the sound I like easily.

Please tell me exactly what the problem is, and if it can be fixed (& by who) or should I just get a new amp? Thanks.

Well this is a lot of good information. I really appreciate the responses.

I suppose I should make a different thread but that seems kind of silly. But anyhow the title would be “which of the really miniature ones stands out?”

That is things along the size of an elf or something that’s not terribly bigger than that. Once again, like I said in the beginning, some thing that would fit in a gig bag . It seems there are quite a few really good amps that are getting closer and closer to the size of an Eden traveler. I do miss my WT 400 but it was also Bigger than what I want to carry around for something like this. In that case it’s not the weight, it’s the physical size. The outside dimensions. You aren’t going to shove that in the side pocket of a gig bag. You’re definitely not going to shove some of the bigger class D amps mentioned here in one either.

I probably threw a lot of people off by mentioning the SWR. It’s simply the smallest amp that I have that I usually take to little practices or what have you. My regular rig is a Demeter 201S and Alembic SF2 going through a QSC 1602 power amp. It’s great but 4 rack spaces and it’s got to be in the 40 something pound range. I don’t mind carrying it. That’s one of the reasons I go to the gym. But I don’t want to bring it everywhere.

I am kind of laughing at myself because for a small/medium size gig I would have no problem bringing a little tiny D class head and my Avalon to get the tone I wanted even though that U5 would be much bigger than the amplifier.

There are many different size gig bags available. Some amps shop with gig bags too.

I do appreciate those padded gig bags made just for amplifier heads of a particular type. I try to get one whenever I can although sometimes it is difficult to find them. In any event, for purposes of my last post I meant something that I can just put in the side pocket of the bass guitar gig bag. I can see owning a few of these type of amplifiers in my future depending upon the need of the particular situation.

Traynor SB-200H is super-tiny and packs a real punch! Perfect size for an emergency backup amp (which is what I bought it for originally). I also currently own a Carvin BX500 and a Carvin MB10 (combo) which have both been ultra-reliable and really just fabulous to play thru ( tone controls and onboard compressor are awesome...)
I've recently acquired the Hartke TX-600 and also the Hartke TX-300 which I both enjoy mainly for their sort of ready-to-use 'right out of the box' sound (which reminds me of the Fender Bassman amps I started out with). Anyway, I have had zero reliability issues with any of these relatively-affordable class-D amps :)

I'm not saying I'd want the amp to take a fall in it or anything although it is padded, but I'm assuming the WD-800 isn't the only one in the Subway line that comes with a bag tailored for it. I use a Gator Pro Go for a gigbag. I could PROBABLY shove my amp in the huge front pocket but I tend to reserve that for cables and straps with the above gigbag around my neck/shoulder, wearing the Pro Go like a backpack I still have two hands free and I'm carrying around 20ish lbs, and it's not the weight of my amp I'm feeling.

I shall step aside now and quit interrupting the search for tiny amps.. just kind of felt like with the feature set, it's capable of doing the job of the little guys yet with enough power to also potentially save you from dragging 40lb racks around at the same time.

Correct, the padded gig bags are designed for light duty transport and are not intended to protect the amp from a fall. This is generally true of all amps/bags.

Pretty much true for instrument gig bags, too... It's to protect from scratches and minor stresses while human carried or in the back seat of the car. Not so much for loading in the truck with the PA or as checked airline baggage.

I mean.. I would never ever ever do this but lol.. I think they got the idea from Mono? Was it Mono gigbags that demod a gigbag like this? *Edit* it was reuinion blues



But yeah.. I accidentally dropped my P-bass in a Fender gig bag/sleeve 2 ft off the ground and dented the finish...which is why I bought one of these. Anyhoo.. sorry OP for getting off topic.

What do you think IvanMike? Everybody's been letting you know what they think. Are you in the market? FWIW I have EA Doubler w/NL210 cab & Fender Rumble 800 w/ it's 210 extension cab. Both deliver volume and tone at gigs.

I am in the process of looking for small, lightweight, 2-Ohm-capable heads equipped with variable high-pass filters, and I cannot see any knobs on the front or back of this unit to adjust the high-pass filter.

How do you adjust the HPF during a gig?
