I plugged it in direct from my guitar, guitar-ME50-Amp.
Im glad you have no problems with the board and hope you get some good sounds.
As for why the hell i would buy it with no intention of using the the distortion, let me give you a little example of the cost where i live of buying the effects on there own:
1- Boss Delay $480
2- Boss EQ $260
3- Boss Chorus $330
4- Boss Harmozier $200
Etc Etc Etc for all the effects on the board...
Boss ME 50 $750
It had ALL the effects which sound great and the value unbeatable. I would be crazy NOT to buy the board because it has distortion pedals which i dont want to use, it was still a heck of Alot cheaper than buying the individual pedals which all would have needed power adapters and cables to add to their already high costs.
So i was real dissapointed when i couldnt just ignore the Distortion and use my Amp's as i loved the ME 50, think its great and was very excited. But thats life, i guess.
Trendkillah and Azrael,
Dedicated units look like the way i have to go, just gradually build up the ones i like at the extra cost. Its a shame as the ME 50 effects, to me, really were as good as the individual pedals. I tested both and the Delay has all the ssame knobs and was particularly good.
