A tiny bit of background to this review. I tried out the Egnater Tweaker 15 head in a shop ages ago and instantly fell in love. Cut a long story short, they didn't have any in stock (and I couldn't afford a new amp), but wow what a little beastie! Just like guitars, it is sometime rare to find an amp that you don't want to stop playing (I had this with the Cornford Roadhouse and Fender Blues JuniorIII recently, although I did try out a Fender Deluxe Reverb which was amazing...but rather too much!). About 12 months ago, I borrowed the Egnater Tweaker 40 Combo, and I used it at home and on a couple of gigs. I thought that it was awesome in terms of it's portability, and at home really liked the the it sounded, but at the gigs there was something missing. One reason for this, was that one of the gigs was in the worst sounding venue of all time, so perhaps I was a little bit harsh on the amp. Long story short, the borrowed amp went back, never to really be thought of again.I have been exceptionally happy gigging for the last couple of years primarily with my Fender Blues Junior III. Who would have thought it for a little 15 W amp, but it works really well with the music we are playing. But...two things, one I am on the eternal quest for the right tone (okay I know what it actually is....my JMP-1 rack with 2 x 12 cab, but it is a little over kill for most gigs, and I can't be bothered to carry it up 3 flights of stairs on a regular basis), and two the Blues Junior is awesome, but sometimes you just want 'that' distortion sound that Fender amps aren't renowned for....and I was kind of in the mood for a bit of that.Having said I always wanted to pick up an amp with a bit more clean headroom, which wasn't too much of an issue with the BJ III, but I was always on the verge of breakup (sorry the amp was...not me personally) and I fancied a little bit more breathing space. The Fender Hot Rod Deluxe III, was always been on the cards as a potential, but I am not really drawn to it for some reason. I tried out the previous version...wow is it loud, but the OD wasn't totally to my taste.So the Tweaker was lurking in the background again, I was also thinking (as we do tend to go in circles) that perhaps a head is the best option, opening up the possibility of different cabs for different jobs. So, I thought I'd give it another chance, and also because I thought of a new way of using it. The big factor in this is the fact you can set up two identical channels....why would you do this??Well...you set up one clean and then one which is basically your clean channel with a bit of a boost, a fantastic situation to be it, especially as you can shape the channel as well. This really appealed to me. But also because I could set up one channel clean, then the second with some lovely amp distortion, and then use a pedal to push for a lead tone, and giving me a slight crunchy tone on the clean too. So many options, and a few more than were possibly with the Blues Junior III which makes a little teensy bit more suitable for live use....for me!So many options! How cool is that, this amp really does deserve sometime spent with it to get the sounds that you want, but believe me, they all seem to work, so much so you are spoilt for choice and it makes it difficult to decide which one to ultimately go with. Currently, I have my heart (and selector switch) set to the Brit tone stack option as it gives me the throaty distortion sound I was looking for. I really like the versitility that this amp gives you to have either two mirrored channels, i.e. you set both up the same, and the perhaps use channel two with a bit more gain an level as a kind of boost. This would work fantastically well if you say were running with some distortion/overdrive pedals before the amp. You have clean/dirt and then clean boost and dirt boost.If breakup is your thing, then with the gain set around 11-12 you can get some lovely crunchy tones. I love how the tight switch...erm tightens up the bottom end (ooer missus!) and give you a much more punchy tone, conversely I like the deep switch engaged to give a lovely thick distortion tone. The shared EQ is a little bit frustrating, I guess the ultimate tweaker would want control over everything. I do like the responsive nature of the EQ thought, it is really hard to dial in a bad sound.I am currently using it with the Ampeg GVT112E 1 x 12 Cab review the cabinet and speaker (Celestion V30) work in perfect harmony, although lacking the metal thump, but hey, I am going for portability here. The amp also takes pedals really well, I used it in conjunction with a old school Boss SD-1 Super Overdrive and this sounded fantastic. In effect creating three levels of boost, with the existing boost switch, giving crunch, distortion and lead tones.Oh and did I mention how small and light this amp is? Throw it in a backpack or a holdall, no more worries about lugging heavy gear. Pair it up with your cabinet of choice and you are good to go! I think my misgivings about the combo were right and I stand by them, but perhaps I didn't allow the little fellow a proper chance. I think the head works better as you can chose your cabinet and perhaps more the speakers that you favour! I guess I should use a higher rated speaker, but I do love vintage 30's and they are in the 0.5 max wattage range.A slight negative for some is that there is no inbuilt reverb, so you will need an external reverb pedal (probably better). I am not really fussed about no reverb as I'd either would add some using TC Hall of Fame, but to be honest unless it is for a special effect, gigging with reverb isn't really a requirement as you are having to deal with the natural reverb of the hall/room/venue.Pros

How many options? SO many!! It is tweaktastic, to your hearts content
Enables you to potentially take 'different' amps to different gigs
It is SO small and light, how cool is that! You can throw it in a backpack
Two channels the same! Enabling to to have variations on a channel (or two very different channels)
Comes with a great footswitch (included!)

Cons

Shared EQ, not a biggy, but would have allow the ultimate Tweakery experience
AC/Brit/USA tone stack applicaple to both channels, shame as it would be awesome to have USA on one and Brit on two!
No protective edges on the side, shouldn't be too much of a problem if you are careful
No reverb...if that's your bag!
