Follow up post - couple of questions - and I did read through the manuals from Boss
1.
Does anyone know the intended characteristics of the SHAPE button in the amplifier section? There are three variations or off. I can hear differences - and it appears that the variations perhaps change based on the selected amp type? There is no associated change in any other setting/eq to see what is going on - or what is the design intent at each setting. The manual seems quite vague about this - did I miss something?
Here is the description from the main manual: "Adds a different tonal character to the amp sound. Pressing the button toggles between the three types (green/red/orange). The effect is off when the indicator is dark."
The tone studio manual is silent on this.
I'm all for experimenting and choosing what sounds best to me - but it would be helpful know the design intent of each setting?
