I am looking for an amp that will be ideal for giging, as currently i have to use the venues or a friends amp which arent good quality most of the time. i have up to £300 to spend but i dont want to be spending all of that as i also want a pedal. the pedal i want is one that will be able t provide a synth sound. however, if any amps can be recommended with effects built in would be great.

Thanks In Advance,
I was looking at the Line 6 spyders, but there seems to be some hate of them in general

EDIT: i dont play much bass anyways so you might not want to listen to me
You can probably get an Ashdown MAG300 combo second hand for between £150 and £225.

For synthy sounds, you could buy a Boss SYB5 for about £50 secondhand.

I'd recommend those two.

Fender Standard Jazz Bass
Artec Matrix Pedal Tuner
BBE Optostomp
Boss GEB 7
EHX NYC Big Muff
Ashdown MAG C410T-300
Torque T100BX
GAS-ing for:
Boss SYB5
Behringer Intelligate IG9
Consentrate on the amp first. Im in the same situation borrowing amps but yes defiantly sepnd all of it on 300 watss of power.
Yamaha TRB1006
Fender MIA jazz bass
Hora Hybrid double bass
Hartke lh 500
Ev 606L
Epiphone les paul
This is about the best rig I can find:
Hartke HA2500
Peavey 115 TVX

And add a cab later.

I think it'd be better to go used, man...you folks across the pond really get shafted.

As for the pedal, look at the Ibanez SB7. All-analog, quite a few tones, and great sound quality. No risk of tracking errors, at all. You really can't beat it in that price range.
Nope, no sig here.
