There is the Nux Air which is suitable for both guitar and bass, has a phone amp for amp sim and effects plus other things. Rechargeable battery, aux in, headphone out, small and compact.
The only review Ihave seen prefered it to the Positive Grid.
I have RS77S fitted to two of my shortcsales: on the one they were fitted to first the dead/out of tune sound is a lot less now than before so I think they may have a longer 'break in' period. Those fitted to my other bass are also starting to sound better over time although they have been on for a shorter period and not played for as long.
The Rotosound strings are made of Monel (Nickel/Copper + a few other components) which is a very different material from steel or nickel so if you take into account the comments from fretmeister:
I would expect to hear a least a tonal difference anyway.
I use a version of the Gear4Music pedalboard unit. The base unit is rechargeable and has a big enough battery to enable it to charge the guitar bug. It also has a built in tuner, rotary 'cable length' simulation and a dc out socket to power another pedal.
The bug also has a mute function.
The battery in the base unit has manged to match the life of the one in the bug, recharge the bug and still have charge remaining after the bug has run out of steam for a second time.Pretty pleased with it so far.
I have been using 50 - 110 gauge (roundwound) and have recently changed to 40 - 90 (flat wound) more than a gauge change I know but I really like them.
A previous rythm guitarist in our band had a Silver Series strat he had bought it off a guy years before he joined us and had never felt the need to change. It was a guitar that just seemed to sound right no matter what it was playing.
I bought a bass from Woz when he moved to Regent Guitars in Leamington Spa. Also purchased a Spector Legend 5 string from Sound Control.
Oh those were the days.
