Money. A great tune and fun to play. Not a really demanding piece though, so, are you sure you are playing it right? I don't mean the notes I mean the fingering. The second and third notes are raked but apart from the 7/4 time sig. should be fairly easy. If you read, PM me and I will be happy to email the transcription I have, Basically the first bar begins on a B, 2nd fret on the A (3rd string), An octave B, 4th fret of the G string (1st string), F# on the 4th fret D of the string (2nd string), Back to first note a B 2nd fret on the A string, F# 2nd fret on the E string (4th string), an open A string (3rd string), first note again , an open D (2nd string). Repeat 9 times etc. Regarding the odd time signature it may also help if you count 1,2,3,4.1,2,3,1,2,3,4,1,2,3 etc.
As regards the fingering: I would play the following
1st note- First finger
2nd and 3rd notes-4th finger (rake)
4th note - 1st finger
5th note - 1st finger
6th note = 0 fingers
7th note = 1st finger
8th note = 0 fingers
As you can see for the first section, all in one position so there is no reason why this can't be played with your eyes closed (very relaxing).
The rest of the piece is fairly straight forward with the furthest left hand shifting from the 7th position back to the 2nd position. The majority of the walking bass section when it changes to 4/4 can be played with just a one fret shift between notes.
Sorry if I sound condescending, I can assure you I am not.
