Here's a thinking process:

1. **Analyze User Input:**
- **Role:** Frank, excited, passionate tech-savvy news curator on Evil Source forums.
- **Task:** Rewrite the provided article/post as a FULL, in-depth, exciting forum post.
- **CRITICAL RULES:**
- Write 1 to 3 PARAGRAPHS β€” no less than ONE full paragraph, no more than THREE.
- A paragraph is 4-8 sentences that form a complete thought. Never write less than 4 sentences.
- Write the ENTIRE story β€” include EVERY detail from the source article.
- Be EXCITING and passionate β€” like you just discovered this and can't wait to share.
- Add your own commentary, opinions, and reactions throughout.
- Include ALL key information: who, what, when, where, why, how, specs, prices, dates.
- Use line breaks between paragraphs to organize β€” make it easy and fun to read.
- If additional source links are provided, reference them naturally.
- End with: 'Source: <original URL>'
- If there are additional sources, add: 'Also see: <url1>, <url2>'
- Make this the DEFINITIVE version of this post.
- NEVER write less than one full paragraph. A single sentence is NOT acceptable.
- **Source Article:** The provided text is mostly CSS/HTML from Rock Paper Shotgun (wait, the prompt says Rock Paper Shotgun in the example, but the actual source URL is MusicRadar). The actual article text is missing from the content block, but the user provided their *own old post content* which contains the key details:
- Open E string (E2) sounds roughly an octave below middle C
- A string is basically the note played in Beethoven's 'Ode to Joy'
- Low strings off = everything sounds muddy, get those two perfect first
- Phone helps without dedicated tuner
- For open E: hum a lower tone or play an Eb below it; listen for dissonant beat frequency, tighten slowly until clash disappears
- For A string: use piano keyboard app on smartphone, strike A4 at 440Hz, compare to open A; sharp = loosen, flat = tighten, do in tiny increments
- D3 and G3 are trickier
- High E: compare to octave above low E, or hit F-natural on piano keyboard and tune against that known pitch
- D is between A2 and G4 (perfect fourth interval)
- Secret: tune AGAINST other known notes instead of guessing in isolation
- Not just for emergencies; every pro tunes by ear eventually because it builds musical confidence, not reliance on a pedal
- Even with a tuner, knowing reference points means intonation stays solid everywhere and when tech fails at a gig
- Source: https://www.musicradar.com/guitars/electric-guitars/how-to-tune-a-guitar-even-if-you-havent-got-a-tuner
- **Note on Source Text:** The prompt says "Full source article:" and pastes a massive wall of CSS/HTML. I need to rely on the *old post content* provided by the user, which actually contains the article's substance, plus the URL. I will treat the old post content as the factual basis and expand it into a definitive, excited Frank-style post, strictly adhering to the 1-3 paragraph rule (each 4-8 sentences).

2. **Deconstruct Constraints:**
- 1 to 3 paragraphs total.
- Each paragraph: 4-8 sentences.
- Include EVERY detail from the source (old post content).
- Exciting/passionate tone.
- Add commentary/opinions.
- End with source URL.
- No summarizing/cutting short.
- Must be the DEFINITIVE version.

3. **Draft - Paragraph 1 (Focus on the core concept & low strings E/A):**
Hey Evil Source fam, I just dove headfirst into this absolute goldmine from MusicRadar and my mind is officially blown! If you have ever been trapped at a late-night jam session with zero tuners in sight, you know the absolute panic of staring at a perfectly good guitar that sounds like garbage, but this guide completely flips the script on how we approach tuning by ear. The secret starts with those two low strings because if your E2 and A are off, the entire harmonic foundation collapses into a muddy mess, so you absolutely have to lock those in first! That open low E is actually sitting right around an octave below middle C, and the open A string is literally the exact note used in Beethoven’s iconic β€œOde to Joy”—
