As a long time Line6 user, bass player, and recent POD Go purchaser, it's great to see that there are a lot more choices available for the bass players over some of the previous generations of Line6 products.
However, given that our guitar playing brethren have a large selection of amp, cab & pedal variations, how about a few more bass specific amps, cabs & pedals, such as a bass specific wah, or a few more bass specific Distortion / Overdrive / Fuzz pedals (with the "Blend" control). Something (but not limited to) like Yamaha & Line6 endorsee, Billy Sheehan's signature EBS drive pedal, which would give us a bit more colour, or one of the Tech21 (Boost Distortion / Boost Fuzz?). What about all the Aguilar or MarkBass range? What about the Ampeg Liquifier & Opto Comp?
Pretty sure there are other bass players out there crying out for a bit more choice & variation in the choices available.
