Hey all,

been having great success with building clones and designing my own pedals recently so I started getting more adventurous, started work on a drive/distortion kinda pedal today based on I think the marshall 18 amp (forgot quite which amp schematic caught my eye) and I stuck it together on the breadboard and got a horrible hiss and low volume, I double and triple checked it on the board and I know it matched the schematic, which brings me to two options, faulty parts of bad concept.

Just wondering if any of you pedal gurus could look over the design and point out any mistakes I've made, cheers
