Can my PSU drive these pedals?

[schmig]

Hi folks,

I currently use the following chain:

- Boss TU-2 tuner
- Some sort of boss compressor
- Sansamp VT bass

These are daisychained starting at the TU-2. Power supply is some sort of Roland/Boss, possibly PSA-120, has a little green LED on in.

I notice that if I chain all the way to the VT bass, the green LED on the power supply starts to flash. I'm not up very well on electrics and presume it can't drive all 3.

This surprises me at the guitarists tend to be driving a load of pedals on the one PSU.

Any clarification from anyone?

Hm, I use a Boss adapater that puts out 200mA and I never had any problem driving more than 3 pedals, one of them being the VT bass.
