Line Level Output to Guitar Amplifier Input

[pattobrien]

Hi All,

I'm working on a project that requires me to plug a line level signal into the input of a guitar tube amplifier. Line level can be a bunch of things in between -10db to +4db, and this amplifier is meant to take guitar input that is generally around -20db (from what I've understood).

Is such a task solvable with just a simple voltage divider circuit? Is there no loss in quality or anything else I should be concerned with? And I'm assuming the output has to be low impedance as well? Thanks for the help in advance!

Input impedance of guitar amps is generally 100k~1Meg. A divider consisting of 10k/1k resistors should fit the job. Keeping in mind the specific sound of a guitar amp, the influence of the divider on sound quality is absolutely neglible.
