Guitar/Bass Driver pcb

As I forgot to order one of the transistors, I have not yet tested the effect, but I have some experience from the making of. But I am expecting a booming sound, when all the crisses and crosses from the assembly will be forgotten.
This thing is SMALL! Too small for my taste really - and I see no real good reason, why. Soldering is tight and you struggle. It suffers so much from its tinyness - putting in transistors is a nuisance, for example. Even bigger nuisance is mounting the pots. And if only their headers would be in standard 2,54 pitch from each other (I made a whole mounting brace with the stripboard) in my head and also bought such pots, but then, baam, the spaces are out of measure - so I made pots on wires).
But the biggest trade-off of this smallish design is the lack of mounting holes - how on earth are you supposed to put this in your chassis - stick it in with a chewing gum? I was seriosly considering the option of using double sided tape to attach it, but then I decided for another option and abused the generous amount of GND pads on the PCB for soldering on solder lugs (a hack that I used on my own (stupidly designed) pcbs without mounting holes and on few stripboard projects)- I will use them with plastic distance bolts for attachment to the chassis.
When I get the Q, which will enable me to test the effect (hope it works), I will write some more.
