Little
Hill
INSTRUCTION MANUAL 1.0
Olsson Amplification 2019 – www.olssonamps.com

"!
Congratulations on purchasing this guitar amplifier designed and built by Olsson Amps in
Sweden.
The Little Hill is a two channel EL84 powered amplifier capable of producing many
styles of music from jazz, blues to classic rock and heavy rock. You will notice, the tight
bottom end and rich harmonically detailed chords and single notes. This amp cleans up
extremely well with the guitar’s volume control, even with the amp on higher gain
settings. The Little Hill takes pedals very well and loves boosts, overdrives, phasers
etc. The Little Hill also has a transparent Series FX loop with adjustable send and return
levels. This amp sounds great at both, bedroom volume levels and at high volume levels.
We are sure that you will love your new Little Hill amplifier. If you have any questions or
need assistance don’t hesitate to email us at [email protected] or call. See our
website www.olssonamps.com for contact details.
