Hello,
I have recently become the owner of a TC Electronic Combo 450.
I must first point out that it took well over a month for the amp to be delivered to me - problems with the shop moving their warehouse and TC sending the head and RS210C separately - so I was eagerly anticipating its arrival.
Once it arrived it was a lot lighter than I had originally thought and the trolley wheels - although feeling a little flimsy - do work very well.
This being my first +£1000 purchase of gear I'm not the most experienced with hi spec amplification but I will try and give a more 'day-to-day life with the amp' review.
Sound wise, I cannot fault this amp, you have a very wide EQ palet with which to work and the ability to change the centre frequencies of all four EQ controls is very useful if you are picky or like to experiment.
Volume wise, I struggled slightly whilst to hear myself over my drummer (not too loud) and guitarist (a little loud), thankfully singer/rhythm guitarist was not there (very f***ing loud) and I had the settings flat with a bit of spectra comp, gain a quarter way round and volume on 8. I was also getting a bit of speaker overload (slightly fuzzy sound when plucking the note) at this volume. I fear that to get a decent amount of volume out of this requires an extra cab, but I am waiting for the editor of Bass Guitar Magazine to get back to me on this - it may be my lack of knowledge which is the problem.
Weight as I mentioned earlier was lighter than expected and the dimensions of the amp make it an easy one for any car boot (if push came to shove I'm sure you could happily rest it on your lap if sat in the back)
Portability as mentioned it is well dimensioned amp and I doubt would have much trouble fitting on smaller stages, through narrow door ways, up narrow staircases etc etc.
The detachable trolley wheels provide an excellent alternative to carrying the amp, although be wary, this amp was not designed for long walks along pavements/car parks - allow me to explain:
My band rehearse at the music/rehearsal facilities on the University of West England Frenchay campus as we are all students there living in the accommodation on campus. It is about a 15min walk from the accommodation to the CPA (rehearsal room facility) on which we have to walk along slabbed pavements and tarmac roads, climbing so very small cirbs along the way.
On my first outing with the amp on this twice weekly migration, I arrived at the CPA to find the wheels had worn into the back of the cab, right down to the wood on both sides. (See Pics) The rubber feet that can be seen in the pictures are not solid enough to stop the wheels from being pushed to rub up against the cab. There were also a few instances where the amp started to wobble from the side to side like it was about to topple most likely due to the wheels being situated behind the cab as opposed to either side - which would create better stability.

Something else which potential buyers should be wary of is the fact that when placing the amp down after using the trolley wheels, you run the risk of damaging the front bottom edge of the cab. I have managed, if a little 'bodge job' esque, to fix this problem by using the right angled cardboard pieces from the box the amp came in. (See Pics) It has been wrapped in duck and electrical tape and fixed using velcro tape - works a treat.

So, anyone looking at getting one best wait til I have spoken to TC to try and resolve these problems.
Check back for updates.
