Does anyone know the weight of the stroke 4? I saw one youtube vid where the fellow said it was 9 kilos, that makes it nearly 20 pounds! Gads for a SS amp that seems rather heavy. Also Is anyone using either of the stroke 4 amps for bass, acoustic and electric guitar? It seems as if the rich EQ section (given a separate reverb / echo / overdrive solution is there) it would be ideal for acoustic and electric guitar. I need clean and have been looking to the steelaire but the price is too hefty for a second travel / backup amp. I found a used one locally at a fair price and have a 4U cab with a 2U space itching to be filled if this will work well for me.
