Quilter Labs InterBlock 45 45-Watt Head

I bought this amp to play solo gigs to backing tracks. I wanted something with no attached speaker that would sound good plugged directly into my PA. This amp does that perfectly for me. It's so small it fits right on my pedal board. It's solid state, but has a very warm and full sound more like a tube amp. Perfect for my Les Paul I actually like it better than my Vox AC10C1. It has low, mid, and high boost or cut tone controls that are very responsive. It has a lot of bottom, so I have that cut a little, mid is flat, and high is boosted a little. It gets plenty loud through my PA but I don't run it through an external speaker so can't comment on that. There is a dedicated speaker out as well as a balanced line out that doubles as a headphone out. That jack has a toggle switch that goes from flat to cab simulated for running direct to the PA. There's also a gain control for overdrive that breaks up well. You won't get high gain metal out of it, but it's nice and crunchy for classic rock. It has an effects loop that works fine, but I prefer to run my pedals in front of the amp. The only con I've found is that the control knobs are kind wobbly and feel like they could break off easily. Other than that, I have no complaints, it's exactly what I wanted at that price point.

The features on this little box are great. The tone is pretty good considering how small it is. It won't compete with a traditional amp, but it has the horsepower to get you out of trouble if your amp fails. I like all the features, including the effects loop. It does what it says it does and the price matches ok. My only complaint is that the knobs feel like they're gonna break off. I would have paid $10 more for sturdier knobs. Doesn't matter much, I bought it, tried it out and put it away. Hopefully will never need it but feel confident if I do. Would also be good for home recording if you need an interface. I might use it for that as well. My other guitar player and I split the cost so we're both covered. A good investment.

I give Quilter the credit, for a solid state micro amp head, it puts out a great, clean sound. Lots of headroom, and the tone controls work well. You can flick a switch between "vintage" and "full eq" which gives it a different voice. It is quiet and quite warm without the "restless sounds" one gets from a tube amp. With an 8ohm guitar speaker, it puts out up tp 33 watts, which is very loud with a speaker rated at 100 db as I am using. If you power a 4ohm guitar speaker, it increases the wattage to 45 watts. Best for studio and recording, jamming with friends etc. But with a mike in front of your speaker, there is no limit to the kind of volume you can achieve, depending on your main PA speakers.

I really wanted this to be my dream pedal board amp but it has a few cons that I can't over look.Let's start with the pros.1) The clean tone of this thing is amazing, add a little bit of reverb and you'll be really happy.2) Preamp pedals sound good through the FX Loop.3) It is small and lightweight.4) Easy to use.Cons1) The knobs and switches feel cheap and have play in them. The knobs also don't feel sensitive enough while turning them to make tone adjustments. The knobs and switches feel so bad/weak/loose that I wouldn't mount this unit on my pedal board. (So it will sit on my speaker cab)2) Tone sounds muffled if you use any pedals through the input. (But they sound fine in the FX Loop)3) The two EQ settings (FullQ and Vintage) sound basically the same.4) The unit doesn't have an on/off switchOverall I'm going to keep it until something better comes along. It is good not great.

I bought this because I have some old combo amps Line6, Crate, Marshal that have issues of some sort. Also, I wanted to get away from all the setting on some of these modern combo amps....I don't want to connect to my phone, I don't want 1000 settings. For me, music is a way to get away from media devices...not attach to them.So I've disconnected the amp head and go straight to the speaker with this little amp on two amps so far. On my 15W Crate, it was rather quiet...this could be the speaker.. again these are old combo amps that I got free or damn cheap. On my 30w Crate it sounds great. Good volume and tone.If you look for YT reviews you will see people testing these on larger amps. For the price, hell of a product I think and it is doing exactly what I needed.

Id say its pretty good for the money. I run a line6 helix with into it and out to a 212 blackstar cab. It is light weight and wish it was built a little more solid.

This is a neat sounding amp, just didn't fit my needs. If you have a nice 1 x 12 or 2 x 12 speaker cab I bet this would sound pretty good. I found the pedals going into the front, just didn't sound right.

Well made. Tremendous features for its size. Lots of tonal options. I like it better without pedals in front but others say it takes pedals well. EQ offers two different tone “stacks”. Some find the controls have a flimsy feel, they seem durable. As pedal size amps go, you’d be hard pressed to find a better option, one that’s easier to use or value for the money

5 stars...takes my cheap pedals well, great tone and awesome features. Smaller than I even expected when it arrived, I was taken aback at its size. I have a 4x12 4ohm and it is awesome at low volume, I have yet to turn it up at jam but it might be loud enough at 4ohms. The headphone feature sounds crappy to my ear but most headphone out of an amp sounds bad from my experience. It fits on my micro pedal board and the power source is also smaller than I was expecting. Note: at first I had the power plugged into the amp only half way as it's actually pretty tight and you have to push it in the whole way with a little force. Arrived on the date expected. I would prefer this over the Microblock 45 as this is a step up.Update: the power supply began fraying at the wires in under a months use, it was handled with care also, but still.I ordered a spare, and the supplier is also mailing me another replacement. Pretty sure having more than one will be handy.
