Logic Pro Setup for Guitarists: Fixing Mono/Stereo Input and Optimizing Scarlett Solo Gain

Panic Index // FRUSTRATED
Technical Depth // CONFIGURATION
RESOLVED
Target Environment
macOS + Logic Pro
Reported Symptom
“Guitar signal audible only in the right channel.”

A client recently reached out for a one-on-one Logic Pro session. As an experienced guitarist, he had just invested in a new Mac Studio and a Focusrite Scarlett Solo audio interface to start recording his music. Despite his passion and a brand-new setup, he was stuck—unable to get a clean, workable recording. His frustration was compounded by a seemingly simple but persistent problem: his guitar recordings were only playing back through the right-hand speaker.

The Problem

The client’s immediate issue was a common one for new users of digital audio workstations (DAWs): a mono vs. stereo input configuration. He had his Scarlett Solo’s input set to a stereo input in Logic Pro, which resulted in the mono signal from his guitar only being routed to one side of the stereo field. This simple oversight was preventing him from enjoying his new setup and making it difficult to proceed with his creative work.

The Solution

After quickly diagnosing the problem, we adjusted the input setting in Logic Pro from stereo to mono. Turning on the Inspector View (A) allowed us to change the input to Input 2 (B). This immediate fix solved the audio playback issue, allowing his guitar to be heard through both speakers.

With his primary frustration resolved, we used the remainder of our session to provide a comprehensive, remote tutorial on recording electric guitar in Logic Pro. We covered a range of key topics to empower him with the skills he needed:

  • Logic Pro Setup: We walked through how to create a new guitar track, ensuring the input was correctly linked to his Scarlett Solo.
  • Optimal Gain Staging: I showed him how to set the ideal gain level on his Scarlett Solo and recommended engaging the “Instrument” button. This crucial step activates the high-impedance (Hi-Z) mode, which is essential for recording electric guitars and ensures a high-quality signal.
  • Multi-Track Recording: We recorded some rhythm chords, and then I demonstrated how to overdub a lead part on a second track, showing him how to build a song layer by layer.
  • Virtual Drummer: To provide a solid foundation for his guitar parts, we introduced Logic’s virtual drummer feature. I showed him how to select different drumming styles and use the “Complexity” and “Intensity” controls to create dynamic parts for verses and choruses.
  • Expanding the Setup: The session concluded with a discussion about future possibilities, specifically how he could connect his Roland keyboard to Logic Pro. We talked about the correct USB and MIDI cables to order and how to record his keyboard as both a rich audio track and a flexible MIDI software instrument.

The Outcome

By the end of the session, the client was no longer just a frustrated guitarist with new gear—he was an empowered home studio artist. He now had a perfectly working system, a new understanding of Logic Pro, and a clear path forward for recording his songs. He was confident in his ability to record his guitars and unlock the full potential of his home studio.

The client was so pleased that he left a fantastic review: “Very helpful – I went from not being able to use logic at all to using it well in 1 hour!”

Paul reinstalled all my lost sample libraries, streamlined the storage on my computer so it works faster and fixed my corrupted disk. it took us a couple of sessions and he was friendly and patient throughout. He never made me feel stupid and never over-explained stuff I already knew - in fact he boosted my confidence. Would highly recommend. I've put him on speed dial!

Paul was brilliant, listened to the issues I had on Cubase and my home studio, worked methodically through potential problems and sorted everything. Amazing service, down to earth and explained everything so I could understand. I am a very happy song writer once again thanks to Paul! Will be using Paul again in the future and highly recommend. Thanks Paul.

Honestly, if you're in any way stuck in a creative block because of the gear you have, you've more questions than answers about what the best setup should be for your flow, or even if you have very nuanced problems in your DAW/with your gear, the service Paul provides is second to none. Besides being an extremely nice guy, he knows his stuff and takes the time to understand what you want to get out of each session and makes sure all is good to go! Can't recommend him enough!

Paul provided as stellar service, worth every penny. I came to him with a genuine issue that was affecting my Logic Pro 11 album project regarding drums and midi maps and he solved my problem most efficiently. He was patient, courteous, quick thinking and highly knowledgeable. I will certainly consider using the service again and thoroughly recommend Audio Support - Thank you Paul - you are a star :)

Working in Reaper. Super knowledgeable, friendly, speaks in easy to understand terms. Paul is helping us DAW newbies get in the game. Paul got my lost plugin files working again as well as showed me how to find missing wave files for projects that were loading incorrectly. Keep this man on speed dial.

Paul fixed in around half an hour some midi keyboard/controller problems I have been trying to solve but have had to live with for around two years! He is very knowledgeable and patient and the Any Desk link worked perfectly. I wish I had found his website sooner and wouldn't hesitate to call on his services again. Rick Grant
